상품 특징

• Standard Specification & Equivalent Grades: This product is the BCuP-3 silver brazing rod containing 5% silver. It is equivalent to the American standard AWS BCuP-3, national standard BCu88PAg, and L205. It possesses good plasticity and is specifically suitable for brazing copper and copper alloy joints that cannot maintain a tight fit. The melting point range is 645°C to 1193°C (1193°F to 1472°F).
• Precise Material Composition & Package Contents: The package includes 20 pieces of 5% Silver Brazing Rods, BCuP-3. The precise alloy composition is: Silver (Ag) 4.8-5.2%; Phosphorus (P) 6.5-7.0%; and Copper (Cu) making up the remainder. This ensures consistent, high-quality performance for professional results.
• Superior Performance Advantages: This low-temperature phosphor silver welding rod features excellent fluidity during the welding process, allowing the molten metal to flow into small gaps for strong, seamless joints. With a low melting point range of 718°C to 816°C (1324°F to 1500°F), it is easy to work with, facilitating straightforward installation and removal when needed.
• Versatile Industrial Applications: The BCuP-3 brass brazing rod is extensively used for brazing copper and copper alloys in critical industries. Key applications include work in motors, air conditioners, meters, the refrigeration industry, HVAC units, electrical machinery, electrical appliances, and eyewear manufacturing. It is also suitable for brazing silver and silver alloys.
• Detailed Specifications & Optimal Usage Parameters: Each rod measures 0.050" thick x 1/8" wide x 10" long. For optimal brazing results, the recommended joint clearance is 0.002" to 0.006". The product has a solidus temperature of 645°C / 1193°F and a liquidus temperature of 800°C / 1472°F, with a fluidity rating of 3, ensuring reliable performance in air conditioning, refrigerator, cold storage, and HVAC unit repairs and manufacturing.
