<p>A method for brazing a plurality of aluminium components (14,16,18,20) of different compositions and masses to an aluminium tube member (12) which includes forming a tube preassembly by fitting the plurality of components (14,16,18,20) on to the aluminium tube member (12) by inserting a stud member (24) of a component in to a tube member aperture (28) with an interference fit. A first brazing paste is applied to preselected component to tube connections of the preassembly. A second brazing paste having a different composition to that of the first brazing paste is applied to the other preselected component to tube connections of the preassembly. The preassembly is passed through a furnace at a temperature of at least 580 DEG C and then subsequently to form a tube assembly.</p> |
