there are metals such as silicon that semi-cunduct, and there are metals that just cunduct such as copper.well, what makes a metal semi-cunduct and just cunduct.how does it work in a semi- cunducter that it generated electricaty? i am looking for particular metals that u find easally. perhaps i made the last question one too broad. thks.
Carbides and Ceramic-metals are hardest ..
Toughness is a measure of resistance to brittle fracture. Titanium is tougher than steel, but is harder to machine, and a LOT harder to weld. Tungsten is harder, but not very tough.
No, not by a long stretch. There are many metals much tougher than steel.
Tungsten is the strongest metal known to man at this time. The name tungsten is taken from the Swedish word, tung sten, meaning heavy stone, and is a tough, steel-gray to white metal. Tungsten carbide is also very strong and used on the tips of cutting tools. Tungsten is however difficult to work with so other alloys are used as well, where high strength is in important issue.
Tungsten carbide is the hardest metal known to man. osmium is the heaviest
