Casting & Forging Comparison


Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape.

Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid state.


The advantages of casting include:


  • No real upper size limit in casting weight

  • Large range of alloy choices

  • As forgings remain solid, custom alloys are far more difficult to get into production whereas with casting, alloys including Chrome, Nickel and Moly can be added at the molten stage.

  • Tooling is often less expensive than forge dies

  • Smaller production runsrequired

  • Complicated/complex parts are no problem


The advantages of forging include:

  • Generally tougher than alternatives

  • Will handle impact better than castings

  • The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues.

  • The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength components.
