Aufhauser PhosCopper Brazing Alloys are free from impurities that cause ruptures or leaks. By providing you with the highest quality products, we ensure the lowest cost of purchase and maintenance.
You don't need brazing flux when using PhosCoppers to braze copper to copper. The phosphorus in these alloys acts as a fluxing agent. However, phosphorus will not act in a similar fashion on other metals. Aufhauser White SilverFlux must be used on all other metals to promote wetting, bonding and flow throughout the joint. Do not use PhosCopper alloys on ferrous or nickel-containing alloys (i.e. steel, iron). Phosphorous will react with iron or nickel to create a brittle joint. Aufhauser controls the phosphorus content to tolerances that exceed industry standards.
