1、Ferrous metal refers to iron and iron alloys. Such as steel, pig iron alloy, cast iron, etc. Steel and pig iron are iron-based alloys with carbon as the main added element, collectively known as iron-carbon alloys. Pig iron is a product made by smelting iron ore into a blast furnace and is mainly used to make steel and castings. Casting pig iron is put in the smelting furnace, that is, to get cast iron (liquid), the liquid cast iron cast into castings, this cast iron is called cast iron parts.

Iron alloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements, iron alloy is one of the raw materials for steelmaking, in steelmaking to do steel deoxidizer and alloying elements additives used.

2、Put the pig iron for steel making into the steel making furnace according to a certain process of melting, that is, to get steel. Steel products are ingots, continuous casting billets and direct casting into a variety of steel castings. Usually referred to as steel, generally refers to rolled into a variety of steel steel. Steel belongs to ferrous metal but steel is not exactly equal to ferrous metal.

3, non-ferrous metals, also known as non-ferrous metals, refers to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum, as well as brass, bronze, aluminum alloys and bearing alloys. In addition in the industry also used chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, etc., these metals are mainly used as alloy add-ons to improve the performance of metals, including tungsten, titanium, molybdenum, etc. are mostly used in the production of carbide for cutting tools. These non-ferrous metals are called industrial metals, in addition to precious metals: platinum, gold, silver, etc. and rare metals, including radioactive uranium, radium, etc.
