clad aluminum brazing materials

Clad aluminum brazing composite material, also known as Al Si brazing material, is the most widely used aluminum based brazing material. The form of clad aluminum brazing materials is clad aluminum plate, strip, foil, etc. Generally composed of core material and clad layer:

  • Core materials are generally composed of aluminum manganese 3 series aluminum alloy, which plays the role of intensity support and heat dissipation.
  • The cladding layer is composed of aluminum-silicon 4000 series alloy 4343, 4045, 4047 or other aluminum alloy, which plays a role in welding or improving the performance of the overall material.

self-brazing aluminum solder

Self-brazing aluminum solder are mainly used in welding of aircraft engine groups, automotive air -conditioning heat exchangers, refrigerated air-conditioning all-aluminum evaporator, condenser, refrigerator freezer, electric aluminum bar and aluminum alloy tubes etc. This product has the following three features:

  • There is no need for welding paste and welding flux during welding, with the advantage of environmentally friendly and efficient.
  • Easily docking the current automation production process requirements.
  • There is no corrosive residue after welding, no need to clean.

Production capacity of Chalco aluminum brazing welding material

  • The raw material for Clad Aluminum Sheet production is aluminum ingot or large flat ingot. The use of large flat ingots can save the aluminum ingot melt. The production links mainly include four processes: melting, hot rolling, cold rolling, and refinement.
  • In the melting and casting process, the aluminum ingot and other trace metals are matched and purified, and heated in the melting and casting furnace to reach the melting temperature, and then combined and purified to form aluminum alloy.
  • The final form of the product is aluminum cladding brazing sheet plate, aluminum cladding brazing Coil strip, aluminum brazing foil. These products are then sent to downstream customers for stamping and welding processes. Finally, various heat exchangers are formed.
