Tin Phosphorus Master Alloy
Tin Phosphorus Master Alloy
Tin Phosphorus Master Alloys boost solder performance in SAC and other alloy ranges. Add a little phosphorus, and oxide formation drops dramatically. As a result, solder joints look cleaner and stronger. You also see less dross building up in solder baths.
We make our Tin Phosphorus Master Alloys with 99.9% virgin Tin and red Phosphorus. This approach ensures reliable quality and consistent analysis every time.
Available in 5%, 3% and 1% Phosphorus, balance Tin.
Available Forms
Our Tin Phosphorus is available in:
4kg waffle plate which is easily broken into small chunks for accurate additions.
5kg Ingots
2.5kg Ingots
80g discs
