Characteristics and Application of Titanium
views, Updated: 2021-09-20
Titanium is a very light yet very tough and corrosion-resistant metal. It maintains its color for life at room temperature. Titanium has a similar melting point to platinum, so it is often used in aerospace and military precision components.
Titanium material properties
Titanium metal has the characteristics of very high strength, excellent corrosion resistance, difficult to cold work, good weldability, about 40% lighter than steel, 60% heavier than aluminum, low conductivity, low thermal expansion rate, high melting point. High purity titanium can be made into all kinds of pure titanium products. Such as titanium powder, titanium rod, titanium plate, titanium tube, and so on. Further details are as follows:
Typical applications of titanium
Titanium can be used to make golf clubs, tennis rackets, portable computers, cameras, luggage cases, surgical implants, aircraft skeletons, chemical appliances, and maritime equipment. Also, titanium is also used as a white pigment for paper, painting, and plastics. In the aspect of coating sputtering, it can be used as the sputtering target, evaporation material, and so on. For example:
Advantages of titanium
Titanium has the advantages of low density, high-temperature resistance, and corrosion resistance. It is resistant to both high and low temperatures. It can maintain high strength in a wide temperature range of - 253 ℃ ~ 500 ℃. These advantages are essential to space metal. Therefore, titanium alloys are often called space metals. It is often used as the shell of the rocket engine and the material of artificial satellites and spaceships.
Titanium is a kind of pure metal. Because of its "purity", no chemical reaction occurs when the substance contacts it. That is to say, because of its high corrosion resistance and stability, titanium will not affect its essence after long-term contact with people, so it will not cause allergy to people. It is the only metal that has no impact on human nerves and taste, so it is called "biomimetic metal".
Disadvantages of titanium
Titanium can combine with oxygen, carbon, nitrogen, and many other elements at high-temperatures. So people used to regard titanium as a "rare metal". In fact, titanium's content accounts for about 6% of the weight of the earth's crust, more than ten times more than the combined copper, tin, manganese, and zinc. The biggest disadvantage of titanium is that it is difficult to refine.
