Abstract

The invention discloses a method for producing a powder-coated aluminum alloy section. The method includes steps of preparing an aluminum ingot and other raw materials; smelting and casting an aluminum alloy round ingot; pouring and sawing; annealing; carrying out extrusion forming; carrying out electrostatic powder coating; baking and the like. Waste aluminum materials are added into raw material ingredients, stability of performance of the aluminum alloy section is facilitated, and possibility that undetected materials are generated during smelting of molten aluminum and affect the quality of the aluminum alloy section is reduced. Besides, surfaces of the aluminum alloy section are subjected to chromation, so that corrosion resistance of oxide films on the surfaces of the aluminum alloy section is improved, and binding force of the aluminum alloy section and coatings is increased.
