Explanation

Duralumin is a strong, lightweight alloy composed primarily of aluminium (about 90-95%), with copper (3-5%) and magnesium (0.5-1%) as the main alloying elements. It was widely used in aircraft construction before modern aluminum alloys were developed. Bronze contains copper and tin, Magnalium contains aluminum and magnesium, and Monel contains nickel and copper.
