Problems solved by technology

[0002] The card slots (such as SIM card trays, memory card trays) and buttons (such as volume keys, shutdown keys) in traditional mobile phones are mostly made of plastic materials. In order to increase their appearance and metal texture, they are coated with a Metallic paint, but due to its low strength and poor wear resistance, it is easy to be damaged or faded due to wear and tear during use
In recent years, mobile phone card slots and button materials made of aluminum alloy materials have emerged as the times require, but most of them are low-end materials based on 3-series aluminum alloys, but the oxidation effect of 3-series aluminum alloys is poor

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy metal processing, and relates to a production process of high-performance 6061 aluminum alloy used for mobile phone card slots and button materials. Background technique [0002] The card slots (such as SIM card tray, memory card tray) and buttons (such as volume keys, power-off keys) in traditional mobile phones are mostly made of plastic materials. In order to increase their appearance and metal texture, they are coated with a However, due to its low strength and poor wear resistance, it is easily damaged or faded due to wear and tear during use. In recent years, mobile phone card slots and button materials made of aluminum alloy materials have emerged as the times require, but most of them are low-end materials based on 3-series aluminum alloys, but the oxidation effect of 3-series aluminum alloys is poor. [0003] Therefore, it is a technical problem to be solved by those skilled in th...
