Abstract

In a method of brazing aluminium or aluminium alloys there is used, as filler material an aluminium-silicon alloy containing 10-15.2 per cent of silicon and in addition 0.005-0.3 per cent of a modifying agent which is one or more of the following metals, alkali metals, tungsten, chromium, cobalt, boron, calcium. This filler material may also contain the usual impurities present in such alloys, namely up to 0.5 per cent of iron, up to 0.5 per cent of manganese, up to 0.5 per cent of zinc and up to 0.5 per cent of titanium.
