    Phosphorus Silver brazing alloy

    We have become popular among our clients by providing wide range of silver brazing alloys in various sizes and finishes. These are passed through strict quality inspection to ensure high tensile strength, corrosion resistance and excellent mechanical properties. Phosphorus silver brazing alloys are widely used in manufacturing of various products like diary equipment, diesel engines, electric appliances, electrical apparatus, fire arms, Geysers etc.

    Phos-Copper (BCuP-2) low cost alloy is suitable for most copper-to-copper or brass joints where good fit-up exists, and the assemblies are not subject to vibration or movement. Developed primarily for use on copper, this alloy may also be used on othernonferrous copper base alloys. This product is used extensively on refrigeration units, air conditioning apparatus, electrical conductors, copper and brass pipe fittings, and other copper and brass equipment. By virtue of its phosphorus content, this product is self-fluxing on copper only applications. A flux should be used when brazing brass or bronze with this product.

    Applications• Applications with joint clearance of .001" - .003"• Refrigeration units• Electrical conductors• Copper and brass fittings• Air conditioning apparatus• Copper and brass equipment

    1. Elimination of gas hole effective.

    2. Low melting point and good fluidity than common red copper.

    3.Good welding process and excellent welding configuration.

    4.stable mechanical properties and good cracking resistance.


    The surface of oil and oxide on the work pieces should be cleansed carefully before brazing . The recommended seam of the brazing joint is 0.03 to 0.075mm.


    Quick heating as soon as possible when brazing, and avoiding deviation of the Cu-P filler metal when heat rate is slow.

    Post treatment:

    Merge the work piece into 10% sulphuric acid to recover the color of copper metal from light gray after brazing.

    We are prime manufacturer of BCuP series brazing alloy.

    BCup Series:

    BCuP-2, BCuP-3, BCuP-4, BCuP-5, BCuP-6, BCuP-7, BCuP-8, BCuP-9

    We could make it in ring, wire, sheet, rod sharp to meet your requirement.

    You are welcome to visit our factory and inspect the quality of the brazing materials.
