1000 words or less is a new structural materials titanium, it has excellent performance, such as density,, only 60% of iron, strength and fracture toughness than the high fatigue strength and good resistance to crack growth, low temperature toughness good, excellent corrosion resistance, some of the highest operating temperature of titanium 550oC, is expected to reach 700oC. Therefore it is in the aviation, aerospace, chemical, shipbuilding and other industrial departments have been increasingly widely used, is developing rapidly. Stronger than the titanium alloy than other light metal, steel and nickel alloys, and this advantage can be maintained to about 500oC, so some of the titanium alloy suitable for manufacturing gas turbine components. About 80% of the production of titanium used in aviation and aerospace industries. Such as the U.S. B-1 bomber's body structure material, titanium about 21%, mainly for the manufacture of fuselage, wings, skin and bearing components. F-15 fighters of the body structure material, titanium alloy with a capacity of 7000kg, about 34% of weight of the structure. Titanium is widely used in aerospace technology, high-performance materials, light weight, high strength, toughness, corrosion resistance is its most notable features. Titanium bolt is also the only high strength, low density, excellent resistance to fatigue and corrosion resistance, and low elastic modulus material, widely used in medical equipment, chemical equipment, military and sports equipment and other fields . Especially suitable for bicycles, car modification, titanium spring characteristics: resistance to corrosion, high temperature, high strength, high elasticity, non-magnetic, low after-effects, reflecting the sensitivity. The use of titanium springs: aviation, military, ships, automobiles, bicycles, motorcycles, oil, chemicals, machinery and electronics, hardware accessories and other industries. Contact QQ: 7
