Phosphor Tin

Composition
4-6% Phosphors, balance Tin

Application
This special alloy is widely used in the production of high - grade tin - base solders. The effect of phosphor Tin for solder is three - fold: grain refiner, flux, dross inhibitor. Especially significant in Phosphor Tin's ability to reduce the formation of dross during soldering operations.

Form:
Waffle ingots weighing approx. 5 kg each .

Packing
500 kg steel drums, 50 Kg wooden cases. Other packing available on request
