Copper alloy certified for AM

Desktop Metal and Sandvik Additive Manufacturing have qualified a chromium zirconium copper alloy for use in 3D printing.

The C18150 alloy is often used in thermal transfer applications, such as electrical connectors, welding electrodes, and other electrical and electronic components.

According to the companies, an international automotive company is now testing a 3D printed part design using the alloy in metal powder form supplied by Sandvik Osprey.

The powder can now be binder jet 3D printed on Desktop Metal’s Production System machine. When manufactured in the machine, the C18150 powder can deliver as-sintered densities of 98-99%, according to Sandvik.

Chromium zirconium copper has improved corrosion resistance and can reportedly withstand service temperatures up to 500°C.
