Forged metals can be softer than cast metals because of how they are made. For example, if a metal is forged from an alloy of one metal that is harder than the other, it will be softer than a solid piece of that same alloy cast in sand
Forging involves heating the metal to a high temperature and then forcing it back into shape. The result is a much softer material with more ductility and less brittleness than its original form.
