Zida za machubu a nkhungu zamkuwa ziyenera kukhala zomwe zimakhala ndi mphamvu zabwino zowonongeka, mphamvu zotopa, kuuma koyenera, kutalika kochepa komanso kutentha kwakukulu kwa conductivity coefficient.Zotsatira zake, zinthu ngati phosphorous deoxidize mkuwa (DHP),CUAG,CR-ZR-CU zimavomerezedwa ndi ogwiritsa ntchito mayiko onse.Zopaka: Mkuwa umakhala ndi kuuma pang'ono komwe kumapangitsa kutsika kwa anti-abrasive katundu.Choncho, malo omwe ali m'munsi mwa nkhungu, kumene kupanikizika kumawonjezeka kwambiri chifukwa cha zipolopolo, zidzakhala zovuta kwambiri.Kuonjezera nthawi ya moyo wa nkhungu zamkuwa, yunifolomu nkhungu pamwamba plating ndi kuuma koyenera kumafunika.Ambiri mwa machubu a nkhungu zamkuwa ang'onoang'ono oponyera ma billet sagwiritsidwa ntchito munjira iliyonse yoponyera pomwe pali chithandizo chokhazikika chamtsinje, chifukwa chake ndizovuta kwambiri kuvala.Timagwiritsa ntchito plating ya chrome kuti tiwonjezere moyo wa machubu a nkhungu.Makulidwe a plating adzayendetsedwa munjira yabwino kwambiri.Ponena za zokutira mbale nkhungu zamkuwa, kutengera zaka zomwe takumana nazo, timatha kupereka zokutira za Cr, zokutira za Ni-Cr, zokutira za Ni-Fe kuti zikwaniritse zofuna za makasitomala osiyanasiyana kunyumba ndi kunja.
