Lembaran Tembaga
Pengenalan Produk
Lembaran Loyang berasaskan kuprum elektrolitik, zink dan unsur surih sebagai bahan mentahnya, melalui pemprosesan dengan jongkong, gelek panas, gelek sejuk, rawatan haba, pembersihan permukaan, pemotongan, kemasan, dan kemudian pembungkusan. Prestasi proses bahan, keplastikan, sifat mekanikal, rintangan kakisan, prestasi dan timah yang baik. Ia telah digunakan secara meluas dalam industri elektrik, automotif, komunikasi, perkakasan, hiasan dan lain-lain
