Abstract

The invention discloses a die casting aluminum alloy. The die casting aluminum alloy comprises main components including, by mass percent, 5.0%-6.0% of Mg, 2.8%-4.3% of Si, 0.5%-0.7% of Mn, 0.36%-0.41% of Er, 0.003%-0.008% of Be and the balance Al and other inevitable impurity elements. The die casting aluminum alloy has the advantages that the yield strength is high, heat conduction performance is excellent, corrosion resistance is achieved, and the die casting and machining performance is excellent. The die casting aluminum alloy is high in strength and excellent in heat conduction performance and can be widely applied to the electronic industry, the electrical industry, the communication industry and the electromechanical industry.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, and in particular to a die-casting aluminum alloy. Background technique [0002] At present, the middle plate, frame and back cover of mobile phone products are mostly made of die-cast aluminum alloy. The thickness of the middle plate, frame and back cover is about 0.5mm, and the thinnest part is only 0.45mm thick. This has very high requirements on the strength and thermal conductivity of aluminum alloys to meet the requirements of use. At present, the types of die-casting aluminum alloys used in mobile phone structural parts include: Al-Zn-series high-strength die-casting aluminum alloys, Al-Si series high-thermal conductivity die-casting aluminum alloys and ordinary ADC12 die-casting aluminum alloys. [0003] Among them, the Al-Zn-Si-Cu-based high-strength die-casting aluminum alloy (with a zinc content of about 17%) has the advantages of excellent fluidity and high yield strength. T...
