Bronze Alloy

3D printing material SLM Solutions’ bronze CuSn10 is a copper-tin alloy with a high elongation and medium hardness. Bronze is characterized by good wear properties and resistance to atmospheric corrosion and cavitation in sea water. Typical applications include components and housings for devices in marine environments.

KEY BENEFITS

Good mechanical properties
Resistance to cavitation in sea water
Good corrosion resistance
Good thermal conductivity
