Brief Introduction of titanium for Aerospace Use

March 2, 2012 - PRLog -- The density of titanium is around 4.5g/cm3, only 60% of steel, titanium's strength is close to the strength of normal steel, some high-strength titanium alloy over the strength of the alloy structural steel. The specific strength of Titanium alloy strength (strength / density) is much larger than other structural metallic materials, it can be machined to parts and components with high unit strength, good rigidity, lightweight. Aircraft engine components, skeleton, skin, fasteners and landing gear.

Titanium is a new structural material, it has excellent overall performance, such as low density (4.5g/cm3), high specific strength and toughness characterization, good fatigue strength and Resistance to crack propagation ability, good low temperature toughness, corrosion resistance outstanding. The maximum operating temperature of some titanium alloys is 550 / C, expected to reach 700 / C. So it is increasingly widely used in aviation, aerospace, chemical, shipbuilding and other industrial sectors, is developing rapidly. (σ0.2 /density) and the temperature dependence of the light alloy, steel, etc., the specific strength of titanium alloys is higher than other light metals, steels and nickel alloys, and this advantage can be kept to about 500 / C, so some of the titanium suitable for the manufacture of gas turbine engine components. My company produces titanium rods, titanium plates: of grade1, grade2, grade3, grade4, grade5, grade23 etc.

About 80% of titanium production used for the aviation and aerospace industry. Such as the United States B-1 bomber's body structure material, titanium alloy is about 21%, mainly used in the manufacture of the fuselage, wings, skin, and bearing components. The material of the body structure of the F-15 fighter, titanium with a capacity of 7000kg, about 34% of the weight of the structure. The structure of the Boeing 757 aircraft, titanium accounts for about 5%, with a capacity of 3640 kg. McDonnell Douglas / produced by the DC10 aircraft, titanium with a capacity of 5500kg, accounting for more than 10% of the weight of the structure. The amount of titanium used in the chemical and general engineering fields: 15 percent of the U.S. accounting for its production, Europe accounts for about 40%. Due to the excellent corrosion resistance of titanium and its alloys, good mechanical properties, as well as the qualified organization compatibility, making it for the production of prosthetic devices and other biological materials.
