TRUER SPHERE – CuSn10 – C0010
CuSn10- powder – CuSn10 (SAE 660) or CuSn12 or CuSn20 is a pre-alloyed bronze powder composed of copper and tin. It is widely used in powder metallurgy, additive manufacturing (3D printing), welding or surface coating. It has high density 8.8g/cm3 (varies with processing) and good electrical conductivity and corrosion resistance.
In powder metallurgy (PM), it can be used to produce sintered bronze bearings, bushings and gears due to its self-lubricating properties.
In additive manufacturing, it is suitable for laser powder bed fusion (LPBF) or binder jetting to produce some complex bronze components.
Our spherical CuSn10 powder can be produced by both Gas atomizing and PREP process.
In addition, typical irregular-shape CuSn10 powder can be produced by water atomizing process which is best suitable for PM parts.
