Characteristics and Application of Titanium
Titanium is a very light, yet very tough and corrosion-resistant metal. It maintains its own 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, etc. 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. The 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. In addition, titanium is also used as a white pigment for paper, painting and plastics. In the aspect of coating sputtering, it can be used as 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 rocket engine and the material of artificial satellite and spaceship.
Titanium is a kind of pure metal. Because of its "purity", no chemical reaction will occur 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 plant nerves and taste, which is called "biomimetic metal".
Disadvantages of titanium
Titanium can combine with oxygen, carbon, nitrogen and many other elements at high temperature. So people used to regard titanium as a "rare metal". In fact, the content of titanium accounts for about 6 ‰ of the weight of the earth's crust, more than 10 times more than the sum of copper, tin, manganese and zinc. The biggest disadvantage of titanium is that it is difficult to refine.
