Koperstrook
Produk Inleiding
Koperplaat gebaseer op elektrolitiese koper-, sink- en spoorelemente as sy grondstof, deur verwerking deur Ingot, warm rol, koue rol, hittebehandeling, skoonmaak van die oppervlak, sny, afwerking en dan verpakking. Materiële prosesse Prestasie, plastisiteit, meganiese eienskappe, korrosie -weerstand, werkverrigting en goeie tin. Dit word wyd gebruik in elektriese, motor-, kommunikasie-, hardeware-, versiering- en ander bedrywe
