ABSTRACT:
An aluminum or aluminum alloy shape for manufacture of heat exchangers is coated with a metallic layer of a zinc-base alloy constituting a fluxless soldering or low temperature brazing material when heated. A process for direct coating of formed aluminum shapes in nascent state includes the steps of providing a non-reactive atmosphere around the shape, providing a coating material of zinc-base alloy and bringing the aluminum shape and the coating material into contact and maintaining the contact at an elevated temperature for a predetermined period of time for forming a coherent coating on the aluminum shape.
