Brazing powder
This listing offers silver-copper alloy brazing powder designed for industrial metal joining applications. The material is available in 150, 200 and 300 mesh sizes, providing controlled particle distribution for consistent flow and capillary action. Supplied in moisture-resistant packaging, it is formulated to minimize oxidation during the brazing process and deliver clean, leak-proof joints.
Silver-copper alloys are standard for high-strength bonding in aerospace, automotive and fabrication sectors due to their low melting points and compatibility with copper, steel and nickel alloys. Typical compositions for this grade include 45-80% silver with copper and zinc balancing elements, while mesh sizes in this range are standard for precision applications requiring uniform powder dispersion. The powder’s melting characteristics are critical for achieving strong, durable joints without compromising base metal properties.
Common buyers include manufacturers of heat exchangers, electrical connectors and aerospace components where structural integrity is non-negotiable. Production-scale users typically source in bulk with packaging tailored for automated dispensing systems. Lead times and incoterms are supplier-specific, so buyers should confirm FOB or CIF terms, port of loading and containerization requirements before ordering.

Sourcing Brazing powder from Hunan Research Institute Of Metallury And Material - China Import Guide
Before ordering, verify the exact alloy composition and mesh size distribution to ensure compatibility with your base metals and joint design. Request a material test report or certificate of analysis to confirm the silver and copper percentages, as these directly impact melting behavior and joint strength. Additionally, check for any proprietary flux additions or binder materials that may affect process parameters.
Confirm the supplier’s incoterms, preferred port of loading and container specifications, as these will influence logistics costs and lead times. For bulk shipments, discuss whether the powder is palletized or supplied in intermediate bulk containers, and clarify any special handling requirements for moisture-sensitive materials. Payment terms, such as TT or LC, should also be agreed upon to avoid delays.
Quality checks should include visual inspection for particle uniformity and color consistency, which can indicate oxidation or contamination. For critical applications, conduct a trial brazing test to evaluate flow, wetting and joint strength under your specific conditions. Request documentation such as ISO or AWS certifications, and ensure traceability is maintained for each batch to support post-process audits.
