The production of titanium and titanium military profile

Titanium has many obvious superior characteristics: density (4.5kg / m3), high melting point (1660 ℃), corrosion resistance, high strength, good plasticity, but also through alloying and heat treatment methods to produce high mechanical properties the variety of alloys, is an ideal material for aerospace engineering structures. With a certain amount of oxygen, nitrogen, carbon, silicon, iron and other elements α phase titanium impurities. Stamping process with excellent performance, good weldability, and heat treatment is not sensitive to the type of tissue has a certain strength at a satisfactory plasticity conditions. Commercially pure titanium content of impurity elements in accordance with the division level. Its main strength depends on the content of oxygen interstitial elements, nitrogen. It has a high corrosion resistance in sea water, but poor in mineral acid. Generally used for manufacturing at a temperature -253 ~ 350 ℃ work discontinuity large variety of sheet metal parts or forgings, can also be manufactured rivets, wire and tubing. Application examples: Industrial use of commercially pure titanium in addition to manufacturing parts, extensive use of titanium alloy. It gets in the aviation, aerospace, chemical, shipbuilding and other industries increasingly wide range of applications, gas turbine component manufacturing, production of biological materials such as prosthetic devices. The density of titanium is generally about 4.5g / cm3, only 60% of steel, titanium's strength was close to the strength of ordinary steel, some high-strength titanium alloy structural strength than a lot of steel. Therefore, the ratio of titanium strength (strength / density) is much larger than other metal structures can be made out of high unit strength, rigidity, lightweight parts and components. At present, aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear.
