Tungsten
tungsten
Tungsten has the highest melting point of all metals (3695 K) and is highly resistant to corrosion. Only some mineral acids are able to corrode the metal. When exposed to air, it forms a protective oxide layer. In alloys, the addition of a small quantity of tungsten can greatly increase hardness. Tungsten also has a very high atomic number which makes it suitable as an anode material in an X-ray tube. Tungsten is a completely safe metal. No special precautions or safety measures are necessary when using and processing tungsten.
