Erosion-Resistant Copper
During the production of erosion-resistant copper material, after being electrolytically refined, chromium (Cr) and zirconium (Zr) elements are added to achieve the desired mechanical properties (hardness, conductivity, etc.). It is manufactured as a material with a smooth surface, dense structure, and high machinability.
It has a hardness of 160 HB in drawn rods, and 130–140 HB in flat bars and plates, and is a material resistant to erosion and corrosion.
