Metal Casting vs. Forging: Choosing the Right Process
A practical guide to choosing between casting and forging for your industrial components.
Understanding the Difference
Both casting and forging are fundamental metal forming processes with different properties and cost structures.
Metal Casting
Molten metal poured into a mold. Excellent for complex geometries with internal cavities.
Advantages
- Complex shapes at lower cost
- Wide alloy range
- Large parts up to several tons
Forging
Metal shaped through compressive forces. Grain structure aligns for superior strength.
Advantages
- 20-30% stronger than castings
- Excellent fatigue resistance
- No porosity
