Cov txawv khooms ntawm lub tshuab tuavnyob ntawmntawm lub tshuab tuav nws tus kheej,uas ua tauyuav ua los ntawm manganese steel, martensitic structural steel (martensitic steel), chrome steel, los yog hlau matrix composites (MMC, xws li ceramic).MMCs yog tsim los ntawm ntau hom hlau thiab tshwj xeeb hom ceramic.
Raws li kev hnav-tiv taus (hardness) ntawm cov khoom siv hlau nce, lub toughness (kev cuam tshuam tsis kam) feem ntau yuav txo.
