aluminum brazing filler material

What is aluminum brazing filler material?
aluminum brazing filler material: a welding method that uses filler metal with a lower melting point than the base metal, after heating and melting, the liquid brazing filler metal is used to wet the base metal, fill the joint gap and diffuse with the base metal to realize the connection.
The aluminum filler metal used for brazing is called aluminum brazing filler material.
 
Basic requirements for aluminum brazing filler material:
① lower than the melting point of the workpiece metal;
② have sufficient wettability (the performance of the solder flowing into the gap);
③Have the proper dissolving and diffusing ability with the workpiece metal;
④ Welded joints should have certain mechanical properties and physical and chemical properties.
According to different melting points, solders are divided into soft solders and hard solders
 
Because the aluminum brazing filler material realizes the organic unity of the solder and the flux, the process of applying the flux is reduced, and the aluminum brazing becomes easy to achieve. Ordinary workers can perform high-quality welding after simple training, and Since the composite material can be welded on an automated production line, the operation time is reduced and the production efficiency is improved.
