Nau'in Gami: A5.13, SIFFOFI MAI TAURARI Lambobin lantarki da Sandunan Walda, A5.13
Ana iya ɗaukar Cobalt Alloy 12 a matsayin wani abu mai tsaka-tsaki tsakanin Cobalt Alloy 6 da Cobalt Alloy 1. Yana ɗauke da mafi girman kaso na carbide masu tauri da karyewa fiye da Cobalt Alloy 6, kuma yana da ƙarin juriya ga yashewa mai ƙarancin kusurwa, gogewa, da kuma lalacewa mai tsanani yayin da yake riƙe da juriya mai dacewa da cavitation. Ana amfani da Cobalt Alloy 12 sau da yawa don haɗa kai ko kuma yana gudana akan Cobalt Alloy 6 ko 1. Babban abun ciki na tungsten yana ba da mafi kyawun halaye masu zafi idan aka kwatanta da Cobalt Alloy 6, kuma ana iya amfani da shi a yanayin zafi har zuwa kusan 700⁰C. Ana amfani da Cobalt Alloy 12 don kayan aikin yankewa waɗanda ke buƙatar jure gogewa, zafi da tsatsa.
