CW0011A

CuAg0,04 is designed for increased thermal stability. The effect of the silver content is to increase the resistance to softening without significantly affecting the electrical conductivity. Good to excellent corrosion resistance. Excellent hot and cold workability; good forgeability. Fabricated by coining, coppersmithing, drawing and upsetting, hot forging and pressing, spinning, swaging, stamping .
