Tungsten bar
It can be used as high-temperature heat source and high-temperature structure accessory.
Main applications:
Manufacture electric light source and electric vacuum accessory.
It can be used for make electrical contact.For stirring purposes in rare earth metals smelting and for making tungsten contacts and parts in electrical light sources making.
Tungsten's unique properties, including a melting point of 3410ípc, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes
Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.
Sifon produces pure and potassium doped (wk type) tungsten rod
The potassium doped products is targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries.

I would send you the detail analysis report for this product if you have interest in it. Or you can call me all round the day at0086--797--8293777
Product specification: 12 *12* (330 to 350)mm.
Uses are as electrodes, heating elements and field emitters, and as filaments in light bulbs and cathode ray tubes. Tungsten is commonly used in heavy metal alloys such as high speed steel, from which cutting tools are manufactured. It is also used in the so-called 'superalloys' to form wear-resistant coatings
