The invention belongs to the technical field of aluminum
alloy metal machining and discloses a production process of a high-performance 6061 aluminum
alloy for
cell phone card slot and key materials.According to the production process, a high-performance 6061 aluminum
alloy plate is obtained through the steps of
smelting and
casting, homogenization treatment,
machining face-milling, hot rolling,cold rolling to the finished product thickness,
solution treatment and
quenching at a continuous
quenching line, manual aging treatment and the like, the tensile strength Rm of the high-performance 6061 aluminum alloy plate reaches 300 MPa or above, the
hardness HV of the high-performance 6061 aluminum alloy plate reaches 90 or above, and on the one hand, the high-performance 6061 aluminum alloy plate has good
machining performance and can be suitable for early CNC machining of the
cell phone card slot and key materials; and on the other hand, the high-performance 6061 aluminum alloy plate hasgood
anodic oxidation performance, can be oxidized into various bright colors and thus is quite attractive, a layer of uniform and luster-consistent protecting film is formed on the surfaces of the materials after oxidation, the
hardness and abrasion resistance of a
cell phone card slot and keys are greatly improved, and the service life of a product is prolonged.
