Titanium alloy, as its name implies, is a kind of nonferrous metal, titanium alloy has been widely used in various fields because of its high strength, good corrosion resistance, high heat resistance and other characteristics. There are many kinds of titanium alloys in the market. How to identify the size and hardness of TC4 titanium alloy tubes, and what is the application of TC4?

The surface hardness of TC4 itself is not high, but the heat when it is processed will cause the material surface to be oxidized, nitrided and carbonized to form titanium oxide, titanium dioxide, titanium trioxide three, mixed skin of titanium carbide and titanium nitride. Titanium carbide is an important part of cemented carbide, the hardness is similar to the tools. Titanium nitride is a kind of wear resistant material, its hardness is not lower than that of the gold coating of ornament. Titanium dioxide is a component of the ceramic glaze, its hardness is not low. Moh's hardness is a kind of measurement methods that is aimed at stone, ore, glass which is not easy to be deformation.

The thermal conductivity of titanium alloy is low, and heat transfer performance is poor. The surface hardness of TC4 is not a problem, it seems that it is easy to be processed, but the temperature is easy to rise in the processing, to appear “tofu into iron” problem.
