Stranded Tungsten Wire For Vacuum Metallizing
The tungsten boats, baskets and filaments are manufactured from high grade tungsten. Of all metals in pure form, tungsten has the highest melting point (3422°C / 6192°F), the lowest vapor pressure at temperatures above 1650°C (3000°F) and has the highest tensile strength. Tungsten also has the lowest coefficient of thermal expansion of any pure metal. This combination of properties makes tungsten the ideal material for evaporation sources. During evaporation, it can alloy with some materials such as Al or Au. In this case, another evaporation source material should be used such as alumina coated boats or baskets. Other materials useful for evaporation sources are molybdenum and tantalum.

Tungsten Electrodes for Tig Welding
Our company is a professional TIG tungsten electrode manufacturer in China. Tungsten electrode is widely used in daily glass melting, optical glass melting, thermal insulation materials, glass fiber, rare earth industry and other fields. Tungsten electrode has advantages in arc striking performance with high arc column stability and low electrode loss rate. The electrode loss of TIG welding under the high temperature generated by arc is quite low, it is called tungsten electrode ablation. This is a normal phenomenon.
Tungsten electrode is used for TIG welding. It is a tungsten alloy strip made by adding about 0.3% – 5% rare earth elements such as cerium, thorium, lanthanum, zirconium and yttrium into the tungsten matrix by powder metallurgy, and then processed by press working. Its diameter is from 0.25 to 6.4mm, and its standard length is from 75 to 600mm. Tungsten zirconium electrode can only be welded in alternating current environment. Tungsten thorium electrode is widely used in DC welding field. With the properties of non-radiation, low melting rate, long welding life, and good arcing performance, Tungsten cerium electrode is most suitable for low current welding environment.
