They may look almost identical—but cast metal and forged metal are made in completely different ways, and that difference can dramatically affect strength, durability, toughness, and performance.
In this episode of History of Simple Things, we explore how metal casting and forging work, where these techniques came from, why forged metal is often stronger, and why manufacturers still choose casting for many important components.
From engine blocks and cylinder heads to crankshafts, gears, tools, and aircraft components, discover why engineers choose one manufacturing process over the other—and what is happening inside the metal that you can't see.
