00:00Tungsten is famous for being extremely hard so how can a regular hacksaw cut
00:04it? Surprisingly pure tungsten can actually be sawn and even filed. But
00:18don't confuse tungsten with tungsten carbide. Tungsten carbide is a compound
00:22of tungsten and carbon and it's much harder. Pure tungsten can still be
00:27machined because cutting tools concentrate enormous force into a very
00:31small area. But forging is different. The entire piece has to deform and tungsten
00:37doesn't soften like steel at ordinary forging temperatures. Even a power
00:41hammer barely changes its shape despite the tungsten being glowing hot. So being
00:46difficult to forge doesn't mean tungsten can't be machined and that's what
00:50makes tungsten so strange. So why?
