5 Interesting Facts About Tungsten
of the crucible so that it remains intact. But again, this is impractical for commercial volumes — and that means, at least for the present time, you just can ’t buy liquid tungsten products. How do facts 1-5 add up?. With all of its unique and interesting properties, tungsten is one of the most widely used of the refractory metals. (And no, it is not a rare earth element, even though for political reasons tungsten can be grouped with those elements that make the headlines &mdash... (read more)
