Alloy hnav - ion reedant txheej yog tsuas yog ntxiv manganese, Nioby Cheebtsam ntawm Carbide yog qhov kev taw qhia kev faib tawm, cov kev coj ntawm cov fibers sib tshuam mus rau saum npoo. Carbide microhardness tuaj yeem ncav cuag HV1700-2000 saum toj no, lub hardness tuaj yeem ncav cuag HRC58-62. Alloy carbide nyob rau hauv qhov kub siab muaj lub zog ruaj khov, kom tswj lub siab tawv, tab sis kuj muaj antioxidant zoo heev, tsis pub dhau 500℃kiag li qub siv.
