2070 – 13 – Summary
Non-ferrous metals offer advantages over ferrous metals because they are stronger, more lightweight, and are used where dependability is essential and ferrous metals just can’t get the job done.
For example, the lightweight qualities of aluminum, titanium, and magnesium make them perfect for use in aircrafts and other applications that require a high strength-to-weight ratio. In fact, magnesium is the lightest nonferrous metal on the market today.
Another quality of some nonferrous metals is their resistance to corrosion. Nickel and zinc, for instance, are used as plating metals and to create galvanized steel.
Although nonferrous superalloys come at a higher cost, they offer unmatched performance at extreme temperatures, making them ideal for use in jet engines, steam turbines, and even nuclear reactors.
While they may not be as cheap as ferrous metals, nonferrous metals often provide superior performance.
