The main elements of 6061 coated aluminum sheet are magnesium and silicon and form the Mg2Si. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron. Sometimes it also can be added a small amount of copper or zinc to increase the strength of the alloy without significantly reducing its corrosion resistance. Usually, 6061 coated aluminum sheet produced by Mirach Coating in the high sales of aluminum alloy materials, because its performance is basically consistent with the various mechanical processing, equipment processing.
