General of Copper

Copper is a ductile metal with very high thermal conductivity, electrical conductivity, ductility, corrosion resistance and surface properties. A freshly exposed surface of pure copper has a reddish-orange color. High-purity copper is used as various wires in the electronics industry, bonding wires for electronic packaging, high-quality audio cables and integrated circuits, liquid crystal display sputtering targets, and ion plating. High-purity copper is also an indispensable valuable material in atomic energy, rockets, missiles, aviation, space navigation, and metallurgical industries. AEM can provide high purity OFC, Cupronickel and alloy products as you requested.
