Koperplaat
Produk Inleiding
Messingplaat gebaseer op elektrolitiese koper, sink en spoorelemente as grondstof, deur verwerking deur middel van staaf, warmwals, koudwals, hittebehandeling, oppervlakreiniging, sny, afwerking en dan verpakking. Materiaalprosesse se werkverrigting, plastisiteit, meganiese eienskappe, korrosiebestandheid, werkverrigting en goeie tin. Dit word wyd gebruik in elektriese, motor-, kommunikasie-, hardeware-, versiering- en ander nywerhede.
