Bandhiga alaabta:
Tuubbooyinka birta ee Alloy-ka ah waa nooc ka mid ah birta birta ah ee aan fiicneyn, waxqabadkeedu aad ayuu uga sarreeyaa birta guud ee birta ah, sababtoo ah nooca noocaan ah ee birta ah ayaa ka kooban isbarbardhigga Cr.
Qaar badan, caabbinta heerkulka sare, iska caabinta heerkulka hooseeya, waxqabadka iska caabinta daxalka maaha mid la mid ah birta kale ee birta ah, sidaas darteed tuubada daawaha ee saliidda, warshadaha kiimikada, tamarta korontada, kuleyliyaha iyo warshadaha kale ayaa si ballaaran loo isticmaalaa.
Alloy birta birta aan seamling ka kooban yahay xubno sida Silicon, manganese, chromium, nikkel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminium, copper, boron, dhul dhif ah iyo wixii la mid ah.
