Research on the Extrusion Process of High Strength and Toughness 6063 Aluminium Profiles for New Energy Vehicles
The influence of extrusion process on the grain structure and mechanical property of 6063 aluminium alloy for new energy vehicles was studied.The results show that the strength,plasticity,bending property,crushing property and etc.,of the hollow thin wall profile of 6063 aluminium alloy are the best under the conditions of the ingot heating temperature 450℃and extrusion speed 9 m⋅min-1.The average grain size of the material reaches 70 μm,and the grain structure is small and uniform.The yield strength(Rp0.2),tensile strength(Rm)and elongation(A50)of 6063 aluminium alloy can reach 221 MPa,253 MPa and 16.9%respectively,and there is no obvi-ous crack after bending test and crushing test,and the high strength and tough aluminium alloy profiles for new energy vehicles can be obtained that meet the application requirements.
