Tungsten is a metal with a wide range of uses. Tungsten Alloy has the highest melting point, lowest vapor pressure and highest tensile strength at temperatures above 1650 degrees Celsius of all metals. It can only be attacked slightly by most mineral acids. It's coefficient of thermal expansion makes it a common choice for glass to metal sealing applications. Tungsten also has low emmisivity.
