Aluminium brzaing and soldering materials


 

Aluminium base brazing filler metal is mainly used for brazing aluminium and aluminium alloy. AI-Si flux-cored wire are substituted for ordinary ER4047 wire, particularly for brazing aluminum parts in refrigeration、air-condition and automotive industry.

Attention:The residue such as grease,oxide etc on the surface and connection must be removed strictly before the brazing.
