Nickel ndi chinthu chofunikira kwambiri popanga chitsulo chosapanga dzimbiri ndipo chimawononga mpaka 50% ya ndalama zonse zomwe zagwiritsidwa ntchito posachedwapa…
Chitsulo cha kaboni ndi aloyi wa kaboni ndi chitsulo wokhala ndi kaboni wokwana 2.1% polemera. Kuwonjezeka kwa kaboni kumawonjezera kuuma ndi mphamvu ya chitsulo, koma kumachepetsa ductility. Chitsulo cha kaboni chili ndi mphamvu zabwino pankhani ya kuuma ndi mphamvu ndipo ndi chotsika mtengo kuposa zitsulo zina.
Mapaipi opanda msoko a chitsulo cha kaboni amagwiritsidwa ntchito kwambiri pakupanga zida za nyukiliya, kutumiza gasi, petrochemical, kupanga zombo, ma boiler ndi mafakitale ena, omwe ali ndi kukana dzimbiri kwambiri komanso mphamvu zabwino zamakanika.
