Por qué las hélices de los submarinos militares no hacen ruido

Imagine a river of golden bronze at over 1,100°C filling a mold the size of a house. It sounds like a movie set, but that's exactly how the propellers of nuclear destroyers and submarines are born. 🚢🔥 Today I'll take you to a military facility where they melt 70 tons of metal in a single operation. I'll explain why ordinary steel would disintegrate at sea, what lethal underwater "cavitation" is, and how a giant milling machine sculpts this bronze monster with watchmaker's precision so that enemy sonar can't detect it. 👇 *Here's what you'll see on today's tour:* 00:00 - A river of metal: 70 tons of golden bronze 00:55 - Why bronze and not steel?
