The pure form tungsten metal is used mainly in electrical applications. Usually tungsten contains small amounts of carbon and oxygen, which give tungsten metal its considerable hardness and brittleness. Metal tungsten is worked by forging, drawing, extruding, or sintering. Of all metals in pure form, tungsten metal has the highest melting point (3,422 °C, 6,192 °F), lowest vapor pressure and (at temperatures above 1,650 °C) the highest tensile strength. Tungsten metal has the lowest coefficient of thermal expansion of any pure metal. Alloying small quantities of tungsten with steel greatly increases its toughness

 

Applications of Tungsten Heating Elements:

 

Tungsten Heating element assembly as a sapphire crystal growth furnace heat source, play a decisive role for AI203 melt forming turbulent flow in crucible, and generate radial temperature gradient. Therefore,high purity,high density and sophisticated production, the rational design of tungsten heater assembly are important significance for sapphire crystal quality control, energy saving and service life.
