Industrial Use of Titanium

                       Industrial Use of Titanium
Titanium is abbreviated by the symbol Ti and is chemical element with the atomic number 22. The element is found in almost all living things, water bodies, soil and rocks. Physically it has lustrous silvery grey white metallic appearance and chemically it has highly resistance to corrosion as stains and tarnish that makes it a highly demandable product for use in various kinds of industries. Because of its excellent resistant feature and light in weight in comparison to other metals, this element is used in several industries including aerospace, agriculture, medical, consumer and architectural applications.
Titanium is primarily used in aircraft and marine applications because of its high strength and resistant to sea water. Around 65% of its total production is used in marine and aerospace industries however there are other industries also which used it rest of the production. Paper industry, toothpaste and in plastic industry, it is widely used for making white permanent pigment. The production of titanium metal is done in four major steps, firstly its ore is reduced into porous form to form a sponge and then it is melted to form ingot. After that ingot is undergoes primary fabrications and converted into plates, bars, pipes and other industrial mill products and in its final stage, these mill products are converted into finished products shapes and sizes.

Element is widely used for making propeller shafts and rigging due to its high corrosion resistance with sea water. For corrosion resistance, it is also used in the power generation, chemical and pulp/paper industry and marine industry. Many industrial applications use chemicals like hydro chlorite, chlorine dioxide, chlorates and chlorites for corrosion, however corrosion resistance is critical, titanium which is fully resistant is best to use. In addition the element is excellent erosion resistant and has higher heat efficiency with a superior light weight ratio to other metals.
The excellent properties of Titanium include- it is as stronger as steel but has half in weight, it is ductile and easily handled, available in number of formats like sheets, sponges, ingots, pipes and etc., it has low thermal conductivity and electrical resistivity, easily burn in air and in nitrogen presence also, physiologically element is non toxic and has no adverse effect on human's body and highly corrosion and erosion resistant element among others one.

It is well known element for its ability to alloy with other metals that improves its durability, strength and lightness. Because of its bio compatibility, it is also used in medical applications such as surgical implants of sockets and hip ball that can stays for 20 years. And for aircraft industry, titanium 6AL-4V alloy is used that accounts 50% of the alloys like aluminium and vanadium and other metals.

Today, titanium is popularly used in jewelry making industry because of its exposure to other metals like silver and gold and corrosion resistant from body oils.

Titanium: The Medical Metal of Choice

                   Titanium: The Medical Metal of Choice
The list of titanium benefits is lengthy. This makes it incredibly useful for a number of different industries, including the automotive, aerospace and architectural worlds. But because titanium resists corrosion, is biocompatible and has an innate ability to join with human bone, it has become a staple of the medical field, as well. From surgical titanium instruments to titanium rods, pins and plates, medical and dental titanium has truly become the fundamental material used in medicine.


Medical Grade Titanium

Titanium 6AL4V and 6AL4V ELI, alloys made of 6% Aluminum and 4% Vanadium, are the most common types of titanium used in medicine. Because of its harmonizing factor with the human body, these titanium alloys are popularly used in medical procedures, as well as in body piercings. Also known as Gr. 5 and Gr. 23, these are some of the most familiar and readily available types of titanium in the US, with a number of distributors specializing in these specific grades.

Ti-6Al-4V and Ti-6Al-4V ELI offer greater fracture-resistance when used in dental implants. The implant procedure begins with the insertion of a titanium screw into the jaw. The screw resembles and acts like the root of the tooth. After an allotted amount of time has passed for the bone to have grown into the medical grade titanium screw, a fake tooth is connected to the implant.


Benefits of Medical Titanium

Strong
Lightweight
Corrosion Resistant
Cost-efficient
Non-toxic
Biocompatible (non-toxic AND not rejected by the body)
Long-lasting
Non-ferromagnetic
Osseointegrated (the joining of bone with artificial implant)
Long range availability
Flexibility and elasticity rivals that of human bone
Two of the greatest benefits of titanium are its high strength-to-weight ratio and its corrosion resistance. Couple this with its non-toxic state and its ability to fight all corrosion from bodily fluids and it’s no wonder titanium has become the metal of choice within the field of medicine.

Titanium is also incredibly durable and long-lasting. When titanium cages, rods, plates and pins are inserted into the body, they can last for upwards of 20 years. And dental titanium, such as titanium posts and implants, can last even longer.

Another benefit to titanium for use in medicine is its non-ferromagnetic property, which allows patients with titanium implants to be safely examined with MRIs and NMRIs.

Osseointegration is a unique phenomenon where your body’s natural bone and tissue actually bond to the artificial implant. This firmly anchors the titanium dental or medical implant into place. Titanium is one of the only metals that allows for this integration.
Uses of Medical Titanium

Most all of us know someone who has required surgery to replace a failing hip socket, shoulder joint or severely broken bone. It’s very likely medical grade titanium was the material of choice for the surgeons when reconstructing these parts of the body. As evidenced in the previous section, natural titanium properties make it a perfect alloy to be used within the body.

Medical grade titanium is used in producing:

Pins
Bone plates
Screws
Bars
Rods
Wires
Posts
Expandable rib cages
Spinal fusion cages
Finger and toe replacements
Maxio-facial prosthetics
Some of the most common uses for titanium are in hip and knee replacement surgeries. It is also used to replace shoulder and elbow joints and to protect the vertebrae following complicated and invasive back surgery. Titanium pegs are used to attach false eyes and ears and titanium heart valves are even competing with regular tissue valves.


Surgical Titanium Instruments

There are a number of characteristics that make titanium the perfect choice for surgical instrumentation:

It’s harder than some steel, yet lighter in weight.
It is bacteria resistant.
Again, it can be used in conjunction with instruments emitting radiation.
Titanium is incredibly durable, giving instruments greater longevity.
Because of these great properties, it is used to create a number of titanium surgical devices:

Surgical forceps
Retractors
Surgical tweezers
Suture instruments
Scissors
Needle and micro needle holders
Dental scalers
Dental elevators
Dental drills
Lasik eye surgery equipment
Laser electrodes
Vena cava clips


Dental Titanium

As mentioned earlier, titanium has the ability to fuse together with living bone. This property makes it a huge benefit in the world of dentistry. Titanium dental implants have become the most widely accepted and successfully used type of implant due to its propensity to osseointegrate. When bone forming cells attach themselves to the titanium implant, a structural and functional bridge forms between the body’s bone and the newly implanted, foreign object.

Titanium orthodontic braces are also growing in popularity. They are stronger, more secure and lighter than their steel counterparts. And of course, medical grade titanium’s biocompatibility makes its use in braces even more beneficial than its competing alloys.

Future of Bio-medical Titanium

It is expected that use within the biomedical industry will only continue to grow for titanium in the coming years.

Molybdenum

                                 Molybdenum
If you don't know what molybdenum is, you're definitely not the only one. Molybdenum is one of the trace minerals and although the body stores this mineral in most body tissues including the brain, liver, spleen, lungs, kidneys, bones and skin, overall the levels inside the body are not that significant.
Molybdenum is a component of the enzymes xanthine oxidarse, aldehyde oxidase and sulfite oxidase. As you might guess from the name, molybdenum helps to break apart the sulfite toxins that build up inside the body. That is one reason why it is believed to have antioxidant characteristics. Sulfites in the body are common because they are regularly included in chemical preservatives. Certain foods and drugs and even protein-rich foods also contain sulfites. When the body is not able to break apart the sulfites that build up, it may react by triggering an allergic reaction.

Like many of the other minerals, molybdenum is necessary to the body's ability to carry out the metabolization of fats, carbohydrates, copper and nitrogen. It also makes up part of the enzymes responsible for metabolizing purines and sulfur. In fact, molybdenum is needed to produce many different enzymes.

Cells need molybdenum in order to function properly. In addition, this mineral helps the body fight off nitrosamines which have been linked to cancer development. Molybdenum helps keep a person alert and it can help keep impotence from becoming an issue. It plays a crucial role in the body's ability to keep blood sugar levels in balance. And finally, it is believed that this mineral helps in the fight against dental cavities and tooth decay.
Once this mineral enters the gastrointestinal tract it is easily absorbed and easily eliminated via the kidneys.

Sources of molybdenum

Beans, dark green leafy vegetables, legumes, peas, beans, cereals, rice, yeast, whole grains, liver, kidney, low-fat milk and hard tap water (hard means the water contains a lot of minerals) are all good sources of this trace mineral. Since the instances of this type of mineral deficiency are rare, it does not have a recommended daily allowance. However, because inadequate levels can lead to a deficiency, it is suggested that adults get 75 to 250 mcg/day.

Symptoms of molybdenum deficiency

Molybdenum deficiencies are extremely rare and the only real chance that one will develop is if a person consumes foods that have been grown in soils that lack this important mineral. However, this type of deficiency does happen and when it does, there are serious symptoms including irritability and an irregular heartbeat. A deficiency can cause a decrease in the amount of urine the body creates, and it can decrease the oxidation rate of fatty acids. Fatigue is another symptom as are problems associated with the mouth, gums and vision. In men, another symptom includes impotence. This type of deficiency can also cause cancer. And because molybdenum is needed to break down the sulfite levels inside the body, a lack of it can cause unwanted substances to build up which can then become harmful.

Applications of Titanium Alloys

                          Applications of Titanium Alloys
When it comes to the usage of alloy metal, titanium is one of the most demandable and common elements used in the industry worldwide. It can be highly strengthened by the alloying process with other metals like steel, manganese, aluminium and vanadium etc. Its excellent properties such as low weight, outstanding corrosion resistant and strong strength in comparison to other metals makes it suitable for various successful applications which include medical, agriculture, aerospace, paper/pulp industry, chemical plant, oil and gas extraction, automobiles, sports and power generation etc.
The strong and light metal, supra alloy of the titanium has become a part of everyday's life that keeps plane in the airs, for medical implants, and as infused with many products around the modern home and buildings. Titanium and its alloy have good heat transfer property and melting points have higher than steel and aluminium. As it is a non toxic element and is generally biological compatible with human tissues, it is widely used for medical implants and implement. One of the critical applications is implementing implants in the human body which cannot readily replace and maintained and for this, titanium alloys are suitable elements to use.

The industrial use of this element is increasing very rapidly as engineers found that it can reduce the total cost of project life cycle. The titanium is exceptionally light weight metal compound with higher strength among other metals and that's why it can do work in just half as much as other metals do in terms of strength and weight. In addition when it is converted to alloy, oxide layer is formed which is excellent corrosion inhibitor in itself as this layer automatically remove when scratching, so for the products like fasteners and screws, this element is ideal to use in industries.

Titanium has its way in sports industry too today several modern golf available in the market are made up of titanium alloy that prevents it from corrosion and as good resistance to stains and nicks it is also used for making cookware. In the power generation plant where polluted water is used to form electricity, titanium will improve the life of the condensers and due to its highly resistance corrosion feature, it reduces the use of corrosion allowance.

Since the beginning of the jet engines and air planes, titanium has been used to meet the crucial and high standard for the strength, metallurgical structure and high temperature performance in the air. For engine rotating applications, it is used with latest and advanced technology to build fan blades that reduces noise and increase efficiency. Nowadays, titaniu7m is also found in the wide range of jewelry, watches, bicycles, clocks and eyeglasses and other consumer products.
