What are the characteristics and uses of titanium?

Titanium is a very special metal, very light in texture, but also very tough and corrosion resistant, at room temperature for life to maintain its color. Titanium, which has a similar melting point to platinum, is used in space. Military precision parts. Adding electricity and chemical treatment produces different colors. Titanium has excellent acid and alkali corrosion resistance in the "aqua regia" soaked in a few years of titanium, still shiny, shining. If the titanium is added to stainless steel, only about one percent, it will greatly improve the rust resistance.

Titanium has low density, high temperature resistance, corrosion resistance and other excellent characteristics, titanium alloy density is half of steel and steel strength; Titanium is resistant to both high and low temperatures. It can maintain high strength in a wide temperature range from -253℃ to 500℃. These are the qualities that space metal needs. Titanium alloy is a good material for the shell of rocket engine and artificial satellite and spacecraft, which is called "space metal". Because of these advantages, titanium has become a prominent rare metal since the 1950s.

Titanium is a pure metal, because titanium metal "pure", so the substance and it contact, will not produce chemical reaction. That is to say, because of titanium's corrosion resistance and high stability, it does not affect its essence after long-term contact with people, so it will not cause people's allergies. It is the only metal that has no effect on human plant nerves and taste, and is known as "biophile metal".

The disadvantage of titanium is that it is difficult to extract. This is mainly because 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, the content of titanium accounts for about 6‰ of the weight of the earth's crust, which is more than 10 times more than copper, tin, manganese and zinc combined.

Material characteristics: very high strength, excellent weight ratio corrosion resistance, difficult to cold work, good weldability, approximately 40% lighter than steel, 60% heavier than aluminum, low electrical conductivity, low thermal expansion, high melting point.

Typical uses: golf clubs, tennis rackets, portable computers, cameras, luggage, surgical implants, aircraft skeletons, chemical appliances and maritime equipment. Titanium is also used as a white pigment for paper, paintings and plastics.
