C11000 Copper Plate is an electrolytic tough pitch (ETP) copper plate meeting ASTM standards, with a minimum copper content of 99.90%. It delivers excellent electrical and thermal conductivity, outstanding formability, malleability, and weldability, making it highly suitable for bending, stamping, and machining. It features good corrosion resistance in atmospheric and freshwater environments, smooth surface quality, and precise dimensional tolerance. Cost-effective and widely available, it is the most commonly used pure copper plate for electrical, thermal, and general industrial applications.
