Teren an kwiv
Pwodwi Entwodiksyon
Fèy an kwiv ki baze sou elektwolitik kwiv, zenk ak eleman tras kòm materyèl anvan tout koreksyon li yo, nan pwosesis pa lengot, woule cho, woule frèt, tretman chalè, netwayaj sifas, koupe, fini, ak Lè sa a, anbalaj. Pwosesis materyèl pèfòmans, plastisit, pwopriyete mekanik, rezistans korozyon, pèfòmans ak bon fèblan. Li te lajman itilize nan elektrik, otomobil, kominikasyon, pyès ki nan konpitè, dekorasyon ak lòt endistri yo
