Mzere wa Brass
Chiyambi cha Zamalonda
Brass Sheet yozikidwa pa electrolytic mkuwa, zinc ndi kufufuza zinthu monga zopangira zake, kudzera pakukonza ndi ingot, kugudubuza kotentha, kuzizira kozizira, kutentha, kuyeretsa pamwamba, kudula, kumaliza, kenako kulongedza. Kugwira ntchito kwazinthu zakuthupi, pulasitiki, zida zamakina, kukana kwa dzimbiri, magwiridwe antchito ndi malata abwino. Zakhala zikugwiritsidwa ntchito kwambiri mumagetsi, magalimoto, mauthenga, hardware, zokongoletsera ndi mafakitale ena
