Abstract
A process of making a shaped product consisting of aluminium or an aluminium alloy comprising the steps of producing an intermediate object by extrusion or rolling and having at least one flat surface, coating the at least one flat surface with a brazing flux retaining coating which is composed of flux particles and a binder containing at least 10% by weight of a synthetic resin based, as its main constituent, on methacrylate homopolymer or a methacrylate copolymer, reshiping of the intermediate object into the shaped product and heating the shaped product to a temperature sufficient to provide at least one brazed connection between defined parts of the shaped products.
