Classification: B-CuSn12

Product Features:

• Good Wettability: Effectively wets base materials (e.g., copper, copper alloys, and some stainless steels) during welding, ensuring high-quality joints with strong metallurgical bonding.

• High Strength: Welded joints exhibit high mechanical strength, meeting structural requirements for load-bearing and vibration resistance.

• Corrosion Resistance: Demonstrates excellent resistance to atmospheric, freshwater, and mildly corrosive environments, ensuring long-term stability of joints in service conditions.

• Moderate Fluidity: Offers balanced flowability at brazing temperatures, filling joint gaps effectively without excessive spreading, enabling precise weld formation.

Applications:

• Machinery Manufacturing:

  • Used for wear-resistant components such as bearings, bushings, gears, and worm gears. Combines wear resistance, high strength, and friction-reducing properties to withstand high loads and moderate sliding speeds, extending component lifespan.

• Shipbuilding:

  • Ideal for marine valves, pump bodies, offshore platform fasteners, and hull structures due to excellent seawater corrosion resistance, ensuring durability in harsh marine environments.

• Chemical Equipment:

  • Suitable for valves, pumps, and other components in corrosive chemical environments, resisting chemical media to maintain operational safety.

• Electrical Engineering:

  • Applied in low-voltage electrical components (e.g., relay spring contacts) requiring balanced conductivity, strength, and corrosion resistance.

Packaging: Iron drums, plastic drums, pallets, custom packaging
Shape: Paste, powder, wire, welding rings.

Note: Used for copper-to-copper brazing.
B-CuSn12, leveraging its self-fluxing capability and superior wettability, serves as an efficient and cost-effective solution in electronics, refrigeration, and hard alloy welding applications.
