Titanium carbide round rods for microdrilling tools
The production process of this round bar is extremely rigorous, from the control of the purity of the titanium carbide powder (purity ≥ 99.5%) to the precise regulation of the sintering temperature (about 1500°C), each step affects the final performance. The finished product has excellent dimensional stability, with a coefficient of thermal expansion of only 6×10-⁶/°C under temperature variations from -50°C to 300°C, which is much lower than that of metal materials, ensuring the accuracy of precision tools in different environments. It is widely used in wear-resistant inserts for automotive moulds, which can withstand long-term high-pressure friction without easy wear and prolong the service life of moulds. Titanium carbide round bar is a high-performance bar made by powder metallurgy process, with titanium carbide as the main hard phase and cobalt or nickel as the bonding phase. Its hardness is as high as HRC85 or above, and its wear resistance far exceeds that of ordinary steel, even in a high temperature environment of 500℃ or above, it can still maintain stable performance. This round bar size precision is very high, diameter tolerance can be controlled in ± 0.01mm, surface roughness as low as Ra0.02μm, very suitable for the production of precision cutting tools, mould cores and so on. In the processing of stainless steel, titanium alloys and other difficult-to-cut materials, the life of tools made of it is 10-20 times that of high-speed steel tools, which can significantly improve productivity.
