Mechanical properties of TC4 titanium alloy materials

Titanium alloy TC4 is composed of Ti-6Al-4V, which belongs to (α+β) type titanium alloy and has excellent comprehensive mechanical and mechanical properties. The specific strength is greater. The strength of TC4 sb=1.012GPa, density g=4.4*103, specific strength sb/g=23.5, while the specific strength of alloy steel sb/g is less than 18. Titanium alloys have 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 l=7.955W/m·K.

use

Because of its good comprehensive performance and excellent corrosion resistance, industrial pure titanium has become an indispensable structural material for numerous industrial parts. As a biological implant material, it has been widely used in clinics since the 1960s. In all the commonly used implant materials, titanium is possible. Titanium is the most promising bioengineering material in stainless steel, cobalt-chromium-molybdenum alloy and titanium because of its density and elasticity approaching that of human bone and its non-magnetic properties. The application of titanium has solved numerous major engineering and technical problems, promoted the progress of science and technology, and brought obvious economic benefits, and the excellent performance and great potential of titanium, and showed its application of a broader prospect.
