Umtya wobhedu
Intshayelelo yeMveliso
Iphepha leBrass elisekelwe kubhedu lwe-electrolytic, i-zinc kunye ne-trace elements njengezinto zayo eziluhlaza, ngokusebenzisa i-ingot, i-hot rolling, i-cold rolling, unyango lokushisa, ukucocwa komphezulu, ukusika, ukugqiba, kunye nokupakisha. Ukusebenza kweenkqubo zezinto eziphathekayo, iplastiki, iimpawu zoomatshini, ukuxhathisa ukubola, ukusebenza kunye ne-tin elungileyo. Isetyenziswe ngokubanzi kumbane, iimoto, unxibelelwano, i-hardware, ukuhlobisa kunye namanye amashishini
