Common used die-casting aluminum alloys are mainly divided into three categories:
Al-Si Alloy: YL102/ A413/305/ADC1/ALSI12
Al-Si-Cu Alloy: YL112/A380/306/ADC10/ALSI8CU3, YL113/A383/383/ADC12
Al-Si-Mg Alloy: YL101/A360/309/ADC3/ALSI10MG
For aluminum-silicon alloys and aluminum-silicon-copper alloys, under normal circumstances, the silicon content is between 6% and 12%, which mainly improves the fluidity of the alloy; the copper content is second, which mainly enhances strength and tensile strength; the iron content is usually between 0.7%-1.2%, within this ratio, the demolding effect of the castings is the best.
It can be seen from its structural composition that such alloys cannot be oxidized and colored, and even if desalinization is used, it is difficult to achieve the desired effect.
However, for aluminum-magnesium alloys, the effect of anodizing is slightly better.
