Bann kwiv
Entwodiksyon pwodwi
Fèy kwiv ki baze sou kwiv elektwolitik, zenk ak eleman tras kòm matyè premyè li yo, atravè pwosesis pa lengote, woule a cho, woule a frèt, tretman chalè, netwayaj sifas, koupe, fini, ak answit anbalaj. Pèfòmans pwosesis materyèl, plastisite, pwopriyete mekanik, rezistans korozyon, pèfòmans ak bon fèblan. Li te lajman itilize nan endistri elektrik, otomobil, kominikasyon, pyès ki nan konpitè, dekorasyon ak lòt.
