Nws yog ib qho alloy uas muaj tooj liab thiab zinc. Bronze: Tshwj tsis yog tooj dag cupronickel, lwm yam tooj liab alloys raug xa mus ua bronze. Feem ntau cov bronze tshwj xeeb muaj cov khoom siv ntau dua, hnav tsis kam thiab corrosion tsis kam tshaj tin bronze. Feem ntau siv yog aluminium bronze thiab beryllium bronze alloys.
Vim muaj cov khoom tshwj xeeb ntawm cov cuab yeej alloy steel, cov cuab yeej alloy steel feem ntau yog siv hauv cov cuab yeej kho vajtse. Cov cuab yeej siv qis qis feem ntau yog siv cov cuab yeej carbon steel, uas muaj qhov zoo ntawm tus nqi qis. S2 alloy steel (feem ntau yog siv los ua cov ntsia hlau taub hau thiab cov ntsia hlau ntsia hlau); chrome-molybdenum steel (feem ntau yog siv los ua cov ntsia hlau); chrome-vanadium hlau (feem ntau yog siv los ua cov qhov (sockets, percussion wrenches, pliers); carbon steel (feem ntau yog siv los ua ntswj ntsia hlau) rau kev ua cov cuab yeej qis).
