Forging / Forging vs Casting
When to Specify a Forging
Forging and casting solve different problems. Forging wins on strength and fatigue; casting wins on geometry and one-off cost. This guide walks the decision so you can specify with confidence.
Mechanical Properties
Forging develops a wrought grain flow that aligns with the part's principal stress axis, delivering higher fatigue strength and impact toughness than the same alloy cast.
Geometry
Casting wins for complex internal cavities, undercuts and large free-form bodies. Forging wins for simple, dense, axisymmetric shapes — shafts, discs, rings and blocks.
Cost & Volume
Casting has near-zero tooling for one-offs. Closed-die forging has high tooling cost that amortizes over hundreds of parts. Open-die forging has near-zero tooling and matches casting for one-offs in simple shapes.
Quality & Inspection
Both routes deliver traceable components inspected to the scope your drawing calls for. Forgings have no inherent shrinkage porosity, so they generally meet tighter acceptance levels.
