CuSn12 is a common bronze casting alloy. It is characterized by its good corrosion and wear resistance. It has virtually the same properties as the material CuSn12-C (CC483K), but this alloy is lead-free. Lead improves machinability in copper alloys. If excellent machinability is important to you, we recommend our CuSn12-C in 250g bars.
The bars are very easy to melt and cast. For ideal casting behavior, we recommend pouring the alloy at 1050-1100°C and adding slag binder for copper-based alloys to the melt beforehand.
As an alternative to the 1kg CuSn12 bars, we offer CuSn8 as lead-free bronze in smaller, 250g bars. If you add another 4-7% tin to this, you will get a similar, also lead-free alloy, with very good casting properties.
The surface of the bars is not polished and therefore somewhat duller. Nevertheless, the material is clean and free of impurities.

The molding sand available in our shops is very well suited as a molding material for bronze castings.
