The Harris 0 (Model 0520R) is a phos-copper brazing alloy designed for cost-effective joining of copper-to-copper connections. Formulated with 7.1% phosphorus and the balance copper, this alloy meets AWS BCuP-2 classifications. It is widely utilized in the HVAC and plumbing industries for its ability to flow quickly and penetrate tight clearances. This 25lb package offers substantial volume for industrial fabrication and large-scale installation projects.<\/p>\n
Harris 0 is characterized by its liquidus temperature of 1475\u00b0F (802\u00b0C) and solidus of 1310\u00b0F (710\u00b0C). The phosphorus content acts as a fluxing agent when brazing copper, eliminating the need for external flux in copper-to-copper applications. However, when joining brass or bronze, a proper brazing flux (such as Stay-Silv white or black flux) is required. This alloy is extremely fluid at brazing temperature, making it ideal for joints with clearances between 0.002″ and 0.007″.<\/p>\n
While highly effective for copper, Harris 0 should not be used on ferrous metals (steel, iron) or nickel alloys containing more than 10% nickel, as the phosphorus can form brittle intermetallic compounds that compromise joint integrity. Additionally, it is not recommended for use in high-sulfur environments which can accelerate corrosion.<\/p>\n
For optimal results, heat the base metal broadly and evenly. Once the joint area reaches the proper temperature, introduce the rod; the alloy should flow rapidly via capillary action. Avoid overheating the rod directly. This 3\/32″ diameter rod provides a good balance of deposition rate and heat control for medium-sized tubing and fittings.<\/p>\n","protected":false},"excerpt":{"rendered":"Economical Copper Brazing Alloy The Harris 0 (Model 0520R) is a phos-copper brazing alloy designed for cost-effective joining of copper-to-copper connections.
