The density of titanium alloy is generally about 4.51g/ cubic centimeter, only 60 of steel, the strength of pure titanium is close to the strength of ordinary steel, some high strength titanium alloy exceeds the strength of many alloy structural steel. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, as shown in Table 7-1. It can produce components with high unit strength, good rigidity and light weight. At present, titanium alloy is used for engine components, skeleton, skin, fasteners and landing gear.
High thermal strength
The use temperature is several hundred degrees higher than aluminum alloy, can still maintain the required strength at moderate temperature, can work for a long time at 450500 temperature these two titanium alloys still have high specific strength in the range of 150500, and aluminum alloy at 150 than the strength decreased significantly. Titanium alloys operate at temperatures up to 500, while aluminum alloys operate below 200.
Good resistance to corrosion
The corrosion resistance of titanium alloy is much better than that of stainless steel when working in humid atmosphere and seawater medium. Resistance to pitting corrosion, acid corrosion, stress corrosion is particularly strong; Excellent corrosion resistance to alkali, chloride, chlorine organic articles, nitric acid, sulfuric acid and so on. But titanium has poor corrosion resistance to reducing oxygen and chromite medium.
Good low temperature performance
Titanium alloy can keep its mechanical properties at low temperature and ultra low temperature. Titanium alloys with good low temperature performance and very low gap elements, such as TA7, can maintain certain plasticity at -253. Therefore, titanium alloy is also an important low temperature structural material.
