Problems solved by technology

[0004] In the production of large quantities of thin-walled parts, the biggest product defect of ADC12 alloy is poor deformation (not enough yield strength), which is manifested as flatness not up to standard, which not only requires a lot of rework and shaping, but also increases costs, affects production, and even fails to meet the requirements. customer request

Abstract

The invention discloses die-cast aluminum alloy, application and a production method of the die-cast aluminum alloy and a recycling method of reclaimed material of ADC12 aluminum alloy. The die-cast aluminum alloy is composed of, by mass, 9.6-12% of silicon, 1-2% of magnesium, 1.1-2% of copper, 0.3-1% of iron, 0.5-1.5% of manganese and the balance aluminum and inevitable impurities. The die-cast aluminum alloy is high in yield strength and low in cost.

Description

technical field [0001] The invention relates to the field of alloys, in particular to a die-casting aluminum alloy, its application and production method, and a method for recycling ADC12 aluminum alloy recycled materials. Background technique [0002] With the rapid development of 3C and automotive products, die-casting aluminum alloys have been rapidly applied. By the 1980s, 68% of aluminum alloy components in the United States were produced by die-casting technology. At present, the die-casting aluminum alloys used in industry mainly include aluminum-silicon alloys, aluminum Magnesium alloys, aluminum-zinc alloys, aluminum-silicon-copper alloys, and aluminum-silicon-magnesium alloys. [0003] Aluminum-silicon-copper alloy has excellent casting properties, such as low shrinkage, good fluidity and small hot cracking tendency, etc. It is one of the most used alloy series in casting aluminum alloys. ADC12 is the most widely used alloy grade among aluminum-silicon-copper allo...
