Kunezinkulungwane zamamaki ensimbi ye-alloy kanye namashumi ezinkulungwane zemininingwane esetshenziswa emhlabeni jikelele. Ukukhishwa kwensimbi ye-alloy kubala cishe u-10% wengqikithi yensimbi ephumayo. Kuyinto ebalulekile yensimbi esetshenziswa kabanzi ekwakhiweni komnotho kazwelonke kanye nokwakhiwa kokuvikela izwe.
Kusukela ngawo-1970, ukuthuthukiswa kwe-alloyizinsimbi eziqinileumhlaba wonke ungene enkathini entsha. Ngokusekelwe kubuchwepheshe obuginqikayo obulawulwayo kanye ne-microalloying metallurgy, izinsimbi zesimanje ezine-alloy high-strength, okuyizinsimbi ze-microalloyed, zenze umqondo omusha.
Ngawo-1980, ukuthuthukiswa kwezinhlobonhlobo ezibandakanya izinhlobonhlobo zezimboni kanye nesigaba sezinto ezikhethekile kwafinyelela umvuthwandaba ngosizo lwezimpumelelo kubuchwepheshe benqubo ye-metallurgical.Ebudlelwaneni obune-in-one bokwakheka kwamakhemikhali-inqubo-isakhiwo-ukusebenza. yensimbi, isikhundla esiphezulu sesakhiwo sensimbi kanye nesakhiwo se-micro-fine siqokonyiswa okokuqala. Kuphinde kubonise ukuthi ucwaningo oluyisisekelo lwensimbi ye-low-alloy seluvuthiwe futhi olungakaze lube khona ngaphambili.Umqondo omusha wei-alloy design.
