Pure
tungsten is a steel-gray to tin-white metal. Tungsten has
the highest melting point and lowest vapour pressure of
all metals, and at temperatures over 1650°C has the
highest tensile strength. The metal oxidises in air and
must be protected at elevated temperatures. It has excellent
corrosion resistance and is attacked only slightly by most
mineral acids.
