Tungsten alloy, nke a makwaara dị ka ihe ndọda dị elu, bụ alloy nwere tungsten ntụ ntụ dị ka isi akụrụngwa na nickel, ígwè, ọla kọpa na ihe ndị ọzọ dị ka ihe inyeaka.Ọdịnaya tungsten na-adịkarị n'etiti 85% na 99%.

Carbide ciment, nke a makwaara dị ka tungsten ígwè, ya bụ, bụ alloy na refractory metal carbide dị ka tungsten carbide dị ka isi ihe na cobalt, nickel, molybdenum na ihe ndị ọzọ dị ka ihe nkedo.Ọdịnaya njide na-adịkarị n'etiti 10% na 20%.
