As it is known to us all, Tungsten is a rare, high-melting metal and an important strategic metal, as important as rare earth .When forged to WC, Its normal temperature hardness can reach 78~82 HRC, and its cutting speed can be 4~10 times higher than that of high speed steel. I. WC in China.Tungsten
Abstract: With the development of industry and manufacturing, the requirements for tools are getting higher and higher. High-speed steel tools can no longer meet the needs of productivity, and then people find that cemented carbide has high hardness and high wear resistance, and then carbide has beg
Many years of rich industry experience and expanding trade demand have made our production capacity continuously improved. At present, our production capacity has reached a relatively high level, and all kinds of products are produced online……
