Titanium is pure metal. Because of the "pureness" of titanium metal, when a substance comes in contact with it, there will be no chemical reaction. In other words, because of the high corrosion resistance and stability of titanium, it will not affect its essence after long-term contact with people, so it will not cause human allergies. It is the only one that has no effect on human autonomic nerves and taste. Metals are called "biophilic metals".
The biggest 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. Therefore, people once regarded 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 the sum of copper, tin, manganese and zinc.
Material characteristics: very high strength, excellent corrosion resistance in weight ratio, difficult to cold work, good weldability, about 40% lighter than steel, 60% heavier than aluminum, low conductivity, low thermal expansion, high melting point.
Typical applications: golf clubs, tennis rackets, portable computers, cameras, suitcases, surgical implants, aircraft skeletons, chemical appliances and marine equipment, etc. In addition, titanium is also used as a white pigment for paper, painting, and plastic.
