Abstract
The 8009 aluminum alloys were fabricated by spray forming and extrusion process. The microstructure and properties of the alloy were investigated by means of metallographic, scanning electron microscope and tensile test. The results indicate that at room temperature, the tensile strength of the extruded alloys can reach 415MPa, the yield strength 345MPa, elongation 22.5%. The tensile strength and yield strength of the alloys decrease with the increasing temperature, the plastic of alloys shows a down-up medium temperature brittleness law.
