Ibipimo byerekana ibipimo byakoreshejwe kugirango hamenyekane imiti ikenewe mu gusesengura ubushyuhe nka: karubone, manganese, fosifore, sulfure, vanadium, titanium, nikel, chromium, molybdenum, niobium, n'umuringa. Igipimo nacyo kigaragaza imiterere yo kwikuramo isabwa kugirango ikoreshwe igeragezwa nko gutanga umusaruro, imbaraga zingana, no kuramba.
