Custom 99.999% 5N High Purity Flat Copper Ignot
Copper ingots are bars made of copper which have been cast into a specific shape, like rectangular, round, square, etc. Tianjin Ruiyuan provides high purity copper ingot composed of oxygen-free copper—also referred to as OFC, Cu-OF, Cu-OFE, and oxygen-free, high-conductivity copper (OFHC)—is formed by melting copper and combining it with carbon and carbonaceous gases. The electrolytic copper refining process removes most of the oxygen contained within, resulting in a compound that consists of 99.95–99.99% copper with less than or equal to 0.0005% oxygen.
