Metal forging is a metal forming process that involves applying compressive forces to a work piece to deform it, and create a desired geometric change to the material.

The forging process is very important in industrial metal manufacture, particularly in the extensive iron and steel manufacturing industry.

A steel forge is often a source of great output and productivity. Work stock is input to the forge, it may be rolled, it may also come directly from cast ingots or continuous castings. The forge will then manufacture steel forgings of desired geometry and specific material properties. These material properties are often greatly improved.

Metal forging is known to produce some of the strongest manufactured parts compared to other metal manufacturing processes, and obviously, is not just limited to iron and steel forging but to other metals as well.

Different types of metals will have a different factors involved when forging them, some will be easier to forge than others. Aluminum, magnesium, copper, titanium, and nickel alloys are also commonly forged metals.

It is important to understand the principles of manufacturing forged products, including different techniques and basic metal forging design.

Metal forging, specifically, can strengthen the material by sealing cracks and closing empty spaces within the metal. The hot forging process will highly reduce or eliminate inclusions in the forged part by breaking up impurities and redistributing their material throughout the metal work.
