Product Description

Environmentally friendly self-brazing Copper solder

1. The research and development background of Environmentally friendly self-brazing Copper solder
The development of replacing copper with aluminum is still limited by the characteristics of the material and has not yet been completely replaced. Therefore, there is a situation in which copper alloys and aluminum alloys coexist in a product. Therefore, the connection of aluminum alloy and copper alloy has become a problem that must be faced directly by replacing copper with aluminum.
Although there are already resistance welding, electromagnetic induction welding and other methods on the market that have solved the connection of some aluminum alloys and copper alloys,
However, there are also certain problems such as the inability to be welded due to differences in pipe diameters, which makes it impossible to completely solve the connection between copper alloy and aluminum alloy.
How to solve the reliable connection of copper alloys and aluminum alloys of complex workpieces is an important topic for Henan Chalco's technology research and development team. Therefore, the highly acclaimed "Environmentally friendly self-brazing Copper solder"
Product series: Cu-95-Y, Cu-85-Y, Cu-78-Y series

3. The Superiority of Environmentally friendly self-brazing Copper solder
1) Stable performance
Since there is no gap, no solder leakage will be caused, and the ratio of solder to solder remains unchanged, so the product performance is stable.
2) Improve welding quality
The welding flux wrapped by seamless copper-aluminum solder will not absorb moisture, so the welding quality is stable, the welding porosity is low, and the pore leakage is less than 10ppm.


4. The Application fields of Environmentally friendly self-brazing Copper solder
1. Power field---welding of aluminum wires and copper joints, copper bars and aluminum foils such as transformers and reactors;
2. Electrical appliances field---welding of aluminum and copper tubes in condensers and evaporators in refrigerators and air conditioners;
3. Aerospace field---aircraft air filter connector, rocket pilot valve connector
4. Others---welding of copper wires and aluminum wires in radiators, motors, batteries, home appliances and other products;
