Kedu ihe bụ tungsten carbide?

Tungsten carbideis nke a makwaara dị ka carbide cimented. Tungsten carbide bụ ụdị ihe alloy nwere refractory tungsten (W) ihe micron ntụ ntụ dị ka isi ihe, na-adịkarị n'ogo n'etiti 70%-97% nke mkpokọta arọ, na Cobalt (Co), Nickel (Ni), ma ọ bụ Molybdenum. (Mo) dị ka ihe nkedo.
