The subject wants to ask, "Is Zn-Al-Mg alloy better or Zn-Mg-Al alloy better?" Zinc, magnesium and aluminum are all good. According to relevant public information, the surface of Zn-Mg-Al alloy and Zn-Al-Mg alloy is easy to form a dense oxide protective layer, which has good corrosion resistance. The production cost of Zn-Al-Mg alloy is relatively high and expensive, while the production cost of Zn-Mg-Al alloy is relatively low and the price is relatively affordable, and Zn-Mg-Al alloy is superior to Zn-Al-Mg alloy.
