CuZn10 (Brass / Tombak) is a solid-solution-strengthened copper alloy with 10% zinc, offering very good cold formability and easy soldering, brazing, or welding. CuZn10 resists stress corrosion cracking well and is widely used in jewelry, architecture, and electrical components. It is also very well sprayable with Impact Innovations EvoCSII cold spray systems, achieving 99% deposition efficiency even at 360 g/min powder feed rate.
