C15100 is a CuZr alloy that can be hardened by cold forming and by precipitation of CuZr – phases during a heat treatment. It has good bendability, excellent hot and cold forming properties, a high strength and a good corrosion resistance. Due to the Zr-precipitations the relaxation properties, even at temperatures up to 150°C are excellent. The electrical and thermal conductivity is excellent. Welding and brazing properties are good, soldering properties are excellent. The alloy is registered in the US by EPA to have good antimicrobial properties.
