Lead-free solder for Aluminum-Copper and Aluminum-Aluminum surface brazing with lead-free solder

Product Name：Lead-free solder for Aluminum-Copper and Aluminum-Aluminum surface brazing with lead-free solder

I. Product packaging, specifications, origin, brand, etc.

Product specifications: According to customer requirements

Product packaging: according to customer needs.

II. Product Description: This product is a new type of lead-free soft brazing solder, with tin as the substrate, adding 9% zinc and a small amount of improved elements, and special flux, the content of which is 1.0-3.5% (wt%), with a low melting point, good tensile strength, shear strength, thermal fatigue properties and joint strength. It is mainly used in aluminum-copper, aluminum-aluminum and special aluminum alloy welding. After the weldability test of China Saipao laboratory, the shear strength of the welded joint is about 66N/mm2, and the maximum wetting force Fmax is about 5N.

Usage: basically can be usd in the traditional lead-free soft brazing solder (SnCu0.7) welding equipment and welding process for welding.

III. The product has the following advantages:

1. Aluminum-copper, aluminum-aluminum surface brazing with lead-free solder: excellent mechanical properties, elongation at break

2. Aluminum-copper, aluminum-aluminum surface brazing with lead-free solder: external dimensions of high precision, unit length weight deviation can be controlled

3. Lead-free solder for aluminum-copper and aluminum-aluminum surface brazing: the products meet the requirements of environmental protection.

4. Aluminum-copper, aluminum-aluminum surface brazing with lead-free solder: the surface is smooth and beautiful, without burrs, inclusions, peeling, cracks and other defects.
