A type of copper with a purity of 99.96% or higher and low oxygen content.It has a very small amount of oxygen (0.001% to 0.005%) and generally refers to high-purity copper that does not contain oxides.. Due to the absence of additive elements, copper's thermal conductivity, electrical conductivity, and workability are all at a high level, but its strength is inferior.The price is the manufacturer's selling price, which is calculated by combining the copper quotation and the processing fee.Yen per kg.
