Titanium Application

Titanium Application

     titanium rod is a new structural material, it has excellent performance, such as low density (~ 4.5gcm-3), strength and fracture toughness than the ratio, strength and resistance to fatigue crack propagation ability, good low-temperature toughness, corrosion excellent performance, maximum operating temperature titanium alloy for some 550ºC, is expected to reach 700ºC. So it gets increasingly widely used in aviation, aerospace, chemical, shipbuilding and other industrial sectors, is developing rapidly. Light alloy, steel, etc. (σ0.2 / density) versus temperature, stronger than the titanium alloy is higher than other light metals, steel and nickel alloys, and this advantage can be maintained to about 500ºC, so some of the titanium is adapted manufacture of gas turbine components. Approximately 80% of titanium production for the aviation and aerospace industries. Airframe structural materials such as the US B-1 bomber, the titanium about 21%, mainly used in the manufacture of the fuselage, wings, skin, and bearing components. Airframe structural materials F-15 fighter, the titanium alloy with a capacity of 7000kg, accounting for about 34% of the weight of the structure. Boeing 757 aircraft structural parts, titanium or about 5%, with a capacity of 3640 kg. McDonnell Douglas (Mc-Donnell-Dounlas) produced by DC10 aircraft alloy with a capacity 5500kg, accounting for more than 10% of the weight of the structure. The amount of titanium in the chemical and general engineering areas: United States accounts for about 15% of its production in Europe accounts for about 40%. Due to the excellent corrosion resistance of titanium mesh and its alloys, good mechanical properties, as well as qualified histocompatibility, making for the production of biological materials such as prosthetic devices.
