Two or more metal or alloy parts (such as catalytic convertor parts) are brazed by melting a homogeneous nickel-based brazing filler alloy containing boron in an amount of not more than 0.2% by weight; converting the molten alloy to a powder of uniform composition; and using the powder as a brazing filler alloy to braze a metal or alloy part to a further metal or alloy part. Typically, the parts are of stainless steel with a relatively high aluminum content; at least one of the parts is generally in the form of a thin foil.
