Export-grade aerospace industry high-quality TC4 titanium alloy round steel polished rod Ti-6Al-4Vdensity4.51g/cm3
The composition of titanium alloy TC4 material is Ti-6Al-4V, which belongs to the (α+β) type titanium alloy and has good comprehensive mechanical properties. Greater than intensity. The strength of TC4 is sb=1.012GPa, the density is g=4.51g/cm3, and the specific strength is sb/g=23.5, while the specific strength of alloy steel is sb/g less than 18. Titanium alloy has low thermal conductivity. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum, and the thermal conductivity of TC4 is l=7.955W/m · K.
The composition of GR5 titanium alloy is Ti-6Al-4V, which belongs to (α + β) type titanium alloy and has good comprehensive mechanical properties. GR5 titanium has the same corrosion resistance and light weight as pure titanium, but better mechanical properties. It is widely used in automobile industry, aviation industry, medical industry, sports industry, etc.
