Izityumli zehamile zidla ngokusetyenziselwa ukutyumza amatye ekalika kunye namatye kwizityalo zeSamente kunye nezityalo zeKwarry.
Iihamile zizinto eziphambili zokunxiba ukutyumza amatye abe ngamancinci amancinci. Ilanga liza kwenza iihamile ngokhetho olulandelayo ukuze zilungele ukutyunyuzwa kwelitye likalika:
1, Manganeseintsimbi
2, Manganese +Tic carbides (ubomi obandisiweyo)
3, Manganese + Ceramic (ubomi obandisiweyo)
4, intsimbi yeMartensitic
5, Martensitic / Chrome Bimetal.
6, intsimbi yeMartensitic + Ceramic. (ubomi obandisiweyo)
