The melting point of the high quality copper of Yilong Hardware Factory is 1083℃, the density is 8.9, five times that of magnesium. The electrical conductivity and thermal conductivity of the copper alloy are second only to silver. It has excellent thermal conductivity, ductility and corrosion resistance, and is widely used in the production of electrical conductivity and thermal conductivity equipment.
