How does the ADC12 die casting aluminium ingot contain copper?
If the amount of Cu is not too high, you can try to buy some A00 aluminum ingots to reduce the content of Cu, but after adding A00 aluminum, other chemicals will also be reduced, but as long as the main ingredients in the range, there will be no problem
If the Cu exceeds the standard, and the quantity of the aluminum ingot is large enough, you can make a batch of low copper alloy mixture. But the above are more complicated. Since the aluminum ingot is not qualified, it is better to be replaced by the aluminum ingot maker
