by far those of standard gray irons. In addition, they have the same advantages of design flexibility and low cost casting procedures of cast irons. Their corrosion resistance is equal or superior to that of gray cast iron and cast steel in many corrosive environments. Its wear resistance is comparable to some
Foundries often specialize in either ferrous alloys, which contain iron, or specific non-ferrous alloys, like precious metals, copper-based, or aluminum-based alloys. Ferrous alloys sort into iron and steel. Cast iron alloys include grey iron, which includes silicon, and ductile iron, which has a type of spherical carbon.
