CuSn4Zn2PS is a RoHS and ELV certified lead-free copper tin zinc casting alloy.
By adding phosphorus and sulfur, the processability of the material is optimized and the lead in the traditional machining copper alloy is perfectly replaced. At the same time, because the material is lead-free, it can be used to produce products directly in contact with drinking water, such as connectors, faucets, valve bodies, etc.
