Different Types of Corrosion Resistant Metal Coatings.
Even when unprocessed, some lightweight alloys present extreme corrosion resistance, but surface treatment in a completed product will inevitably be necessary for performance, durability, and quality purposes. Magnesium is famous for its low corrosion resistance. Still, what is least known is that it is equally open to some aluminum alloys and other high-strength families having copper or other transition metals.
