The strongest metal on Earth is tungsten. A hard, rare metal under standard conditions when uncombined, tungsten is found naturally on Earth only in chemical compounds.
In tungsten's raw form, it is a hard steel-gray metal that is often brittle. If made very pure, tungsten retains its hardness and becomes malleable enough that it can be worked easily by forging, drawing or extruding. Of all metals in pure form, tungsten has the highest tensile strength and the highest melting point at 6,192 Fahrenheit. Tungsten is used for filaments in lamps, to create wires in electronics and in the production of steel alloys.
