professional titanium products manufacturer

The composition of titanium alloy TC4 material is Ti-6Al-4V, which belongs to (a+b) type titanium alloy, and has good mechanical properties. Its strength is large. The strength of TC4 sb=1.012GPa, density g=4.4*103, the specific strength sb/g=23.5, and the specific strength of the alloy steel sb/g is less than 18. The thermal conductivity of titanium alloy is low. The thermal conductivity of titanium alloy is 1/5 of iron and 1/10 of aluminum, the thermal conductivity of TC4 is l=7.955W/m / K. The titanium alloy's elastic modulus is low, the elastic modulus of TC4 is E=110GPa, which is about 1/2 of steel, so it is easy to deform when it is processed.
