Metallic character
Hard alloy is higher than the hardness of iron and stainless steel, second only to diamond And, the proportion of W (W: 19.3) is very large, more than twice the iron or copper, and Au (gold: 19.3) about the same weight
How to made of Hard alloy?
Cemented carbide is W (tungsten steel) made from carbon compound WC powder, the combination of Fe as material, in 1300 ~ 1500 ℃ high temperature sintering
What is the hard alloy
Hard alloy is very the hardness very high alloy. Cemented carbide is a W, Mo, Cr, Ti, Zr and Hf, V, Nb, Ta, nine kinds of carbon and Fe (Fe, Co, Ni) on the combination of metal alloy, generally refers to the WC - Co alloy
