Features of aluminium clad fin strip
Large specifications, multiple varieties, small batches
Low hydrogen, slag, and alkali metal content
High uniformity
Small difference in core surface grain size
Small component segregation
Brazing composite material ingots are replaced with steel bands by welding to avoid misalignment of the coating layer during lifting, heating, and billeting
