Nice thought, but forging steel isn’t the only way to shave weight off a wing. You’d need to balance tensile strength, fatigue life and thermal stability. For drones, high‑strength aluminum alloys or carbon‑fiber composites usually win because they give the best strength‑to‑weight ratio and are easier to shape for lift. Still, a well‑heat‑treated steel core could work if you’re building a heavy‑lift or rugged platform where a little extra weight is acceptable. Focus on the grain structure and keep the design as simple as possible to preserve agility.
