Copper Brazing Rod Material is primarily composed of high-quality electrolytic copper. It boasts a natural red copper color, a solid and smooth texture, and is free of oxidation spots or impurities. It comes in round or flat strips and is a metal joining material specifically designed for brazing.
Copper Brazing Rod Material is made from electrolytic copper with a purity exceeding 99.9%, effectively improving electrical and thermal conductivity. This purity standard complies with the BCu alloy classification in AWS A5.8, ensuring the weld joint is free of impurities, enhancing weld reliability and mechanical properties.
With a melting point range of 640°C to 890°C, it exhibits excellent wetting and filling properties during heating, enabling complete joint filling in the shortest possible time. This makes it suitable for precision welding of complex structures or narrow gaps, improving process efficiency.
The brazing process results in a dense, porosity-free weld with excellent oxidation and corrosion resistance, making it particularly suitable for connecting copper pipes or equipment exposed to humid or corrosive environments, ensuring long-term stability.
Copper Brazing Rod Material offers copper-based brazing filler metals with varying phosphorus content, such as BCuP-2, BCuP-3, and BCuP-5, depending on the application. BCuP-5 contains 15% silver, reducing its melting point to 645-815°C, making it particularly suitable for high-end refrigeration and air conditioning systems.
Copper Brazing Rod Material is manufactured without the addition of harmful elements such as cadmium. It complies with RoHS and REACH regulations, making it suitable for export to regions with stringent environmental requirements, such as the EU and North America, while also ensuring the health and safety of operators.
In the air conditioner manufacturing process at Gree and Midea, high-purity copper brazing filler metal is extensively used to connect copper tubes to ensure tightness and thermal conductivity in the piping system. Copper Brazing Rod Material enables rapid filling during high-temperature welding, significantly improving production efficiency.
Copper Brazing Rod Material is widely used in commercial refrigeration equipment from Haier and Panasonic. It is primarily used for the assembly of condenser and evaporator copper tubes, requiring leak-free welds and high pressure resistance. Copper Brazing Rod Material maintains weld stability between -40°C and +150°C.
In the assembly of industrial heat exchange systems at Trane and Carrier, copper brazing rod material is used to connect large-diameter copper tubes and elbows. The welds must withstand long-term high pressure and thermal expansion and contraction. Copper Brazing Rod Material can meet system pressure requirements exceeding 10 bar.
Copper conductor connections in ABB and Schneider electrical equipment require guaranteed electrical conductivity and mechanical stability. Copper Brazing Rod Material enables precise positioning and secure connections, reducing resistance losses and improving the safety level of the conductive system.
Copper components such as Kohler and TOTO faucets and heating pipes require high-strength brazing. Copper Brazing Rod Material, due to its excellent wetting properties and anti-leakage performance, is widely used in the connection process between pipe threads, pipe ends, and copper sheets.
