  • Are forged metals softer than cast metal?

No, forged metals are generally harder and stronger than cast metals of the same alloy, not softer. This is due to the manufacturing processes: casting involves pouring molten metal into a mold, which can result in a coarser grain structure, potential porosity, and inclusions that reduce mechanical properties. Forging, by contrast, uses compressive forces to deform the metal, refining the grain structure, eliminating voids, and aligning the material's internal fibers for better density and uniformity.

Exceptions can occur with specific high-carbon alloys (e.g., cast iron may have inherently higher hardness than low-carbon forged steel due to composition,  but for equivalent materials, forging consistently enhances hardness and overall performance. This makes forged parts ideal for high-stress applications like automotive components or tools, though they are more expensive to produce.
