Material	Tungsten
	Tungsten (W from wolframite) has the highest melting point of any metal (3410 C), and thus it is characterised by high strength at elevated temperatures. Disadvantages are high density, brittleness and poor resistance to oxidation. Tungsten and its alloys are used for applications involving temperatures above 1650 C (e.g. nozzle throat lines in missiles, hottest parts of jet and rocket engines). The filament wire in incandescent bulbs is made of pure tungsten by powder technology.
