Bomba la aloi ni aina ya bomba la chuma isiyo imefumwa, utendaji wake ni wa juu zaidi kuliko ule wa bomba la jumla la chuma isiyo na mshono, kwa sababu aina hii ya bomba la chuma ina Cr zaidi, upinzani wake wa joto la juu, upinzani wa joto la chini, utendaji wa upinzani wa kutu ni bora zaidi kuliko zingine. Bomba la chuma , hivyo bomba la alloy hutumiwa sana katika mafuta ya petroli, anga, kemikali, nguvu za umeme, boiler, kijeshi na viwanda vingine.
