Tungsten
Metal Wire and Boat
Properties of Tungsten:
Tungsten has the highest melting point and lowest vapor pressure
of all metals, and at the temperatures over 1650°C has the highest
tensile strength. It has excellent corrosion resistance and is attacked
only slightly by most mineral acids.
Tungsten is the most useful material used in vacuum evaporation technique,
due to its special properties and cost factor.
