ABSTRACT:
A composition for brazing aluminum or aluminum alloy characterized in that said composition contains aluminum alloy powder for brazing and thermoplastic acryl-based resin binder which is so volatile as to volatilize before being carbonized at a brazing temperature and said resin binder of 0.1 to 50 parts is used for aluminum alloy powder of 100 parts. When this technological idea was applied to brazing with a brazing material of aluminum alloy powder such as, for example, Al-Si, a preferable result of brazing could be obtained.
