Silverfos 52 is a copper phosphor alloy used to weld copper with copper.
Compared to Silverfos 5 it has a greater fluidity and penetration capacity due to the higher percentage of phosphorus. Due to its phosphorus content, the use of the deoxidizer is not required for copper/copper brazing: in case of copper-brass or copper-bronze junction, the use of dissonant is required. It is usually used in heating, air conditioning, refrigeration, heat exchangers, mechanical equipment, electric motors, transformer winding, production and repair of household appliances. Not suitable for applications in contact with sulfides. Not suitable for Fe and Ni alloys.
