Aluminum alloy die-casting aluminum alloy materials are mainly divided into aluminum-silicon alloy, aluminum-silicon-copper alloy, aluminum-magnesium alloy three kinds of materials:
Al-Si alloy: mainly contains YL102 (ADC1, A413.0, etc.), YL104 (ADC3, A360);
Aluminum silicon copper alloy: mainly contains YL112 (A380, ADC10, etc.), YL113 (3830), YL117 (B390, ADC14)
Aluminum-magnesium alloy: mainly contains 302 (5180, ADC5,) ADC6 and so on.
For aluminum-silicon alloy, aluminum-silicon-copper alloy, as its name implies, except aluminum, the composition of silicon and copper are the main components; usually, the silicon content of 6-12%, mainly to improve the liquid alloy flow Sexual role; only the second copper content, mainly to enhance the strength and tensile strength of the role; iron content is usually between 0.7-1.2%, within this ratio, the best mold release effect; through its composition It can be seen from the composition that it is impossible to oxidize such alloy, and even if desiliconization is used, it is difficult to achieve the desired effect. For aluminum-magnesium alloy, it can be oxidized, which is an important feature that distinguishes it from other alloys.
Aluminum alloy die casting currently commonly used A380, A360, A390, ADC-1, ADC-12 and other materials. ADC12 equivalent to the United States ASTM standard A383, while the A380 is equivalent to the Japanese standard ADC10. In Japan, ADC12 is widely used, but in the United States, A380 is widely used, the two components are also closer, but the difference between the content of Si larger, ADC12 9.5 ~ 12%, while the content of A380i 7.5 ~ 9.5% In addition, there are some differences in the content of Cu. ADC12 is 1.5-3.5%, while A380 is 2.0-4.0%. The other components are basically the same.
