Phosphorus-copper-tin rod
"Copper-phosphorus-tin solder belongs to phosphorus-copper solder, with low melting point and better fluidity than other phosphorus-copper materials. It is widely used in the brazing of statistical copper alloy parts in refrigeration, electrical machinery, instrumentation and other industries. Parts can be applied to brazed joints with larger clearances. Brazing methods include flame brazing, furnace brazing, induction brazing and resistance brazing.
