Al brazing filler metals copper wire
Al brazing filler metals copper wire from Qixing Group is an aluminum-silicon eutectic alloy wire with controlled additions of copper, zinc, manganese and magnesium. Designed for joining L2 to L6 purity grade aluminum and alloys such as LF21, LF1 and LD2, it achieves strong, leak-proof joints in aluminum assemblies through flame, furnace or vacuum welding processes. The alloy composition is engineered to lower the melting point and improve flow characteristics at brazing temperatures between 570 and 620 degrees Celsius.
This filler metal is supplied as a continuous wire, typical diameters range from 1.0 to 3.0 mm with a standard tolerance of ±0.05 mm, suitable for automated and manual feeding systems. The aluminum-silicon base provides good wetting on aluminum substrates while the copper and magnesium additions enhance joint strength and corrosion resistance. It meets typical industry standards for brazing filler metals, including AWS A5.8 for aluminum alloys, and is commonly used in HVAC, automotive radiators, refrigeration units and aerospace fabrication where aluminum-to-aluminum joints are required.
Contract manufacturers and fabrication shops use this wire for aluminum extrusion brazing in heat exchangers, condensers and structural assemblies. Buyers should confirm the exact alloy composition and diameter for their application, as well as the recommended flux type for their specific brazing method. The product is typically supplied in coils of 5 kg to 25 kg, vacuum-sealed to prevent oxidation, and should be stored in a dry environment to maintain its properties.

Sourcing Al brazing filler metals copper wire from Qixing Group - China Import Guide
Before ordering Al brazing filler metals copper wire from Qixing Group, verify the exact alloy composition and diameter to ensure compatibility with your base materials and brazing equipment. Request a mill test certificate or third-party lab report to confirm the chemical analysis and mechanical properties of the wire, as these directly impact joint strength and performance.
Confirm logistics details such as lead time, Incoterms (e.g., FOB or CIF) and payment terms directly with Qixing Group. For international shipments, clarify whether the supplier can provide vacuum-sealed packaging and moisture barriers to prevent oxidation during transit. Typical lead times for specialized brazing wire may range from 4 to 8 weeks, depending on order volume and custom specifications.
Quality checks should include visual inspection for surface defects, diameter consistency and coil integrity upon receipt. For critical applications, conduct a trial braze to evaluate wetting, flow and joint strength under your specific process conditions. Request documentation such as material safety data sheets (MSDS) and compliance certificates for industry standards like AWS A5.8 to ensure the product meets your technical requirements.
