Copper Phosphorus or Phos-Copper is used in non-ferrous goods manufacturing industry for introducing phosphorus in the alloy compositions. The introduction of phosphorus deoxidises and refine the alloys. The phos-copper is a homogenized alloy, which is manufactured using pure materials in compliance with international standards ensuring consistent pick-up of phosphorus material.

Application

Brazing Alloys, Welding Electrodes, Phosphor Bronze, Refining of Hypereutectic Aluminum Silicon Alloys, Deoxidized Copper and Copper Alloys.

Tin Phosphorus is used while producing tin solders. It introduce phosphorus in the alloy and acts as a flux, grain refiner and dross inhibitor.
