Alloys can be broadly classified into two groups based on their iron content- ferrous and non-ferrous alloys.
The base metal for some alloys is iron and they are known as ferrous alloys. Carbon steel, alloy steel, stainless steel, tool steels and cast iron are a few examples of ferrous alloys. Alloys that do not contain any iron are called non-ferrous alloys. Out of non-ferrous alloys, there are a large number of copper alloys. Most copper alloys are brasses and bronzes. Most kinds of brass can easily be shaped and have a pleasing appearance.
Other non-ferrous alloys include alloys of aluminium, titanium, zinc, nickel, cobalt, tungsten, precious metals, and refractory metals. They have a wide range of applications ranging from construction work to the manufacturing of medical equipment.
