Abstract

1376778 Brazing VEREINIGTE ALUMINIUM-WERKEAG 25 Aug 1972 [2 Sept 1971] 39878/72 Addition to 1373384 Heading B3R [Also in Division C7] The fluxless brazing of aluminium or aluminium alloy is performed in a non-oxidizing atmosphere or an atmosphere containing little oxygen using a brazing alloy of aluminium with 4-20% silicon, 0À00001-1À0% beryllium and optionally 0À01-10% of one or more of bismuth, strontium, barium and antimony.
