Problems solved by technology

[0002] The preparation methods of aluminum alloy mobile phone shells mainly include die-casting, extrusion + CNC, stamping and other processes. Among them, it is difficult to obtain good anodizing effect for die-casting aluminum alloy. Although extrusion + CNC process can obtain better anodizing effect, CNC The processing volume is large and the cost is high, while the stamping process not only has the advantage of low cost of the die-casting process, but also can obtain a better anodic oxidation effect, so it has gradually become the preferred solution for mobile phone casings
[0003] At present, 6063 with better forming performance is generally used in the industry as the raw material for stamping and forming mobile phone casings. However, as smart phones gradually become larger, thinner, and multi-functional, and the size of mainstream screens continues to increase, larger screens require Higher-strength materials are used for support. The traditional 6063 can no longer meet the strength requirements of the existing shell, and the formability of other high-strength aluminum alloys cannot meet the requirements. Therefore, it is urgent to develop a high-strength And the aluminum alloy with excellent stamping performance is used to make high-performance aluminum alloy mobile phone casing

Embodiment 1

[0025] Preheat the furnace temperature, add 86.6Kg of 99.97% pure aluminum, after the pure aluminum alloy is melted, raise the temperature to 800°C, add 10Kg of Al-5%Co master alloy, 2.5Kg of Al-20%Si master alloy, and drop the temperature to 700°C , add 0.9Kg of pure magnesium, press the pure magnesium into the bottom of the melt for 2-3 minutes until the pure magnesium melts, then raise the temperature to 730-750°C, add refining agent at the same time to refine and remove slag, let stand for 10Min before pouring. After the ingot is uniformed at 550°C / 5h, it is extruded into profiles of required specifications. After 2 passes of 480°C / 4h annealing + cold stamping, 520°C / 4h solution treatment, after water quenching, 180°C / 8h aging treatment.

Abstract

An aluminum alloy mobile phone shell is made of an aluminum alloy material which comprises 0.8%-1.5% of Mg, 0.4%-0.9% of Si, 0.2%-1.2% of Co, and the balance Al and inevitable impurities. The aluminum alloy material for manufacturing the aluminum alloy mobile phone shell comprises 0.8%-1.5% of Mg, 0.4%-0.9% of Si, 0.2%-1.2% of Co, and the balance Al and inevitable impurities. A method for manufacturing the aluminum alloy mobile phone shell comprises the step of forming the aluminum alloy mobile phone shell through the aluminum alloy material. The aluminum alloy material is especially suitable for manufacturing the mobile phone shell with the high-strength requirement, and meets the requirements of thin-walled shell members with high appearance and performance requirements.
