I ezahlukene impahlas wezinsimbi zokushayancikeemigqeni yokushaywa uqobo,okuyinto angakwaziyenziwe ngensimbi ye-manganese, insimbi yesakhiwo se-martensitic (insimbi ye-martensitic), insimbi ye-chrome, noma izinhlanganisela ze-metal matrix (MMC, njenge-ceramic). Ama-MMC akhiwe ngezinhlobo ezahlukene zensimbi nezinhlobo ezikhethekile ze-ceramic.
Njengoba ukumelana nokugqokwa (ukuqina) kwezinto zensimbi kukhula, ukuqina (ukumelana nomthelela) ngokuvamile kuzokwehla.
