C7026 Type CuNi2Si Copper Alloy Strips
C7025 (CuNi3SiMg) is a kind of copper alloy with high strength and high conductivity, especially in the later stage of alloy manufacturing process. This effect is like calendering again, which makes the material harder and stronger, and increases the conductivity and elongation at the same time.
