Titanium shaped parts are used for mechanical accessories, made of titanium as raw materials, so, what is the role of titanium shaped parts?
Pure titanium is a silver - white metal, which has many excellent properties. With a density of 4.54g/cm3, titanium is 43% lighter than steel and slightly heavier than the venerable light metal magnesium. The mechanical strength is about the same as steel, two times greater than aluminum and five times greater than magnesium. Titanium is resistant to high temperature, melting point 1942K, nearly 1000K higher than gold, nearly 500K higher than steel.
Titanium is a chemically active metal. When heated, it can react with O2, N2, H2, S, halogen and other non-metals. But at room temperature, the surface of titanium is easy to form an extremely thin layer of dense oxide protective film, can resist strong acid and even aqua regia, showing strong corrosion resistance. As a result, ordinary metals become riddled with acid while titanium remains unharmed.
Liquid titanium dissolves almost all metals, so it can be alloyed with many metals. When titanium is added to steel, it is strong and elastic. Titanium forms interstitial compounds or intermetallic compounds with Al, Sb, Be, Cr, Fe, etc.
Planes made of titanium carry more than 100 more passengers than planes made of other metals of the same weight. The resulting submarine can resist seawater corrosion as well as deep pressure, and its diving depth is 80 percent higher than that of stainless steel submarines. At the same time, titanium is not magnetic, will not be found by mines, has a good anti-monitoring role.
Titanium is biophile. In the human body, can resist the corrosion of secretions and non-toxic, to any sterilization methods are adapted. Therefore, it is widely used in the manufacture of medical instruments, such as artificial hip joint, knee joint, shoulder joint, hypochondriac joint, cranium, active heart flap and bone fixation clip. As new muscle fibers wrap around these "titanium bones," they begin to support the body's normal activities.
With above excellent features, titanium shaped parts are widely used in the human body, aerospace, marine, chemical industry and tuning car, motorycle etc.
