Problems solved by technology

If the solution heat treatment is not carried out, cracking will occur due to insufficient plasticity during the punching and embossing process. Even if there is no cracking, the phenomenon of orange peel will occur on the surface due to the decrease in plasticity, which will seriously affect the appearance.
If the solid solution is carried out again, the cost will inevitably increase and the production efficiency will be low. At the same time, the disappearance of the extrusion effect after solid solution will cause performance degradation.
[0004] If the extrusion outlet temperature is lower than the quenching point temperature, so that the material cannot be f...

The high-strength aluminum alloy material has the advantages of high strength, good elongation percentage, good welding performance and good chemical polishing performance.

Description

technical field [0001] The invention relates to an aluminum-zinc-copper-magnesium-zinc aluminum alloy material, in particular to a high-strength aluminum alloy material suitable for motorcycle rims. Background technique [0002] Aluminum alloy materials are rarely used in the main structure of general motorcycles, but with the continuous evolution and maturity of technological progress and processing technology, aluminum alloys are gradually being used by more manufacturers as an alternative material. For motorcycle aluminum rims, 7XXX series alloys are selected for material selection. [0003] Due to the low solidus line of 7XXX materials, the extrusion quenching temperature is low. For subsequent processing, the outlet temperature should be controlled lower than the quenching temperature during extrusion, otherwise the material will rapidly deteriorate due to the high alloy content of 7XXX alloys. For natural aging strengthening, the aluminum rim bending, punching and...
