Pure Tungsten
-
Heating Resistors are used as heating components to plate the substrates of kinescope,mirrors,plastics,metal and various decorations.Stranded wires are used as raw material of heating elements,and also as heating components of semiconductors and vacuum devices directly.
-
There are three types of tungsten balls–pure tungsten ball, tungsten alloy ball and tungsten carbide ball.
Pure tungsten ball has the highest density among tungten balls, which iis over 19.2g/cm3. Pure tungsten ball also has the highest melting pointing. -
Tungsten boat/crucible is mainly used in metallurgical industry, machinery processing, glass and ceramic industries, as well as containers for coating materials
-
A tungsten contact disc is treated by burnishing, so as to smooth and compact the contact surface and remove the surface-crazed metals and oxides, while simultaneously filling the surface pores with a contaminant such as iron. The contaminants present in the pores are subsequently removed by immersing the contact disc in a dissolving agent, and the remaining natural oxides of the tungsten are removed from the walls of the pores by cathodic reduction, to create large pore sites, which are free of oxides and contaminants.
