COYOUCO Phosphor Copper Brazing Rods 2.5x500mm Round Welding Rods Low Melting Point High Fluidity for HVAC Air Conditioning Refrigeration,30 Pcs

These phosphor copper round brazing rods are specially designed for precise and reliable copper to copper and copper to brass joints. Made from high-quality phosphor copper alloy, they feature self-fluxing properties, eliminating the need for additional flux when brazing copper components. Each rod measures 2.5x500mm, providing consistent performance for both professional and DIY applications.FeaturesThe round design ensures smooth flow into small gaps, strong adhesion, and leak-resistant joints. The alloy’s high phosphorus content improves capillary action, resulting in a durable and secure bond. These rods are ideal for HVAC repair, refrigeration systems, plumbing, and pipe soldering.SpecificationsMaterial: Phosphor copper (P: 6.6–7.4%, Cu: balance)Shape: Round brazing rodsSize: 2.5x500mmSolidus: 1310°F (710°C), Liquidus: 1508°F (820°C)Recommended joint clearance: 0.002–0.007 inchesApplicationsPerfect for air conditioners, freezers, evaporators, heat exchangers, water heaters, and general HVAC maintenance.
