Product Description

tungsten needle is a tungsten product that is made of a pure tungsten or tungsten alloy electrode material and is sharpened at one end.
Grinding range: tungsten diameter 0.5mm-6.0mm
Sharpening angle: 10° - 90°
Length range:5~330mm
Usage: for tungsten grade argon arc welding, electron probe components, cathode discharge needle, iodine tungsten lamp, bromine tungsten lamp, automotive H series, halogen tube, etc.
Variety: straight, pointed, round, flat

1. discharge material:pure tungsten and cerlum-tungsten.
2. Can supply 99.95% and 99.98% pure tungsten
3. suply shapes as needle,rod, disc, bar and electrode etc
4. The Cerlum-tungsten electrode is a tungsten electrode product which is prepared by adding powdered metallurgy and calendering and polishing process to the tungsten base. It is the earliest non-radioactive tungsten electrode product produced in China. The product is characterized by low current conditions. Excellent arcing performance, small arc current. Therefore, it is often used for the welding of pipes, stainless steel products and small precision parts. Under low current DC conditions or electrode diameters below 2.0 mm, Cerlum tungsten electrodes are the preferred alternative to tantalum tungsten electrodes.
