Ukuvaleka kwezinkambu, ukuvaleka kwezinkambu kuyinto enkulu kakhulu kwezindlu zomlando, okungaphansi kwezinhlelo zokwenza imali zomsebenzi, ukuthengiswa kwezikhathi kwezokwenza umsebenzi kungakwazi ukuthuthukisa ukusebenza kwezikhulu, futhi kungakwazi ukuthuthukisa ukuphila komsebenzi wokuhlangabezana nokwethula kwezindlu ukuze kwenziwe kahle kakhulu. Ikhala lethu lisebenzisa ukudala okuphezulu kwezindlu zokugcina izithombe zomhlaba nokugcina, ngokwesilinganiso esincane, umsebenzi ongaphansi kakhulu usebenzisa ukugcina okugcwele, ngokwesilinganiso esikhulu, futhi umsebenzi ongakhulu usebenzisa ukugcina okugcwele. Izinkambu zisebenzisa ukugcina okugcwele ukuthi ziqinisekise ukulungiswa. Isithombo sikhomba ukuthi isikhumba esikhulu se-alloy yokulungiswa (ZG40CrMnNiMoSiRe).
