Audited Supplier Tungsten has the advantages of high melting point, high strength and hardness, high temperature performance, low resistivity, small expansion coefficient, small electronic power and so on. It is a widely used high temperature resistant metal material.
Pure tungsten products mainly refer to the use of pure tungsten powder (tungsten content ≥99.95%) made of various shapes, including all levels of pure tungsten products and all kinds of sintering, forging, tempering rod, bar, plate, block and tungsten crucible. Our company can mass produce all kinds of pure tungsten tube, rod, plate, ingot, crucible and all kinds of special-shaped products.
Advantages:
High melting point, high hardness, high density, good thermal conductivity, good electrical conductivity, etc.
Tungsten needle production process:
Tungsten powder with high purity is selected to be pressed into a round rod blank, and then the outer diameter and cone are grinded by an external grinding machine after sintering.
Tungsten needle application:
Anion discharge tungsten and tungsten needle needle (cathode), tungsten needle electrode, are widely used in the purification dust, in addition to static electricity and welding industry, concrete can be used in the negative ion air purifier, lampblack purifier purify dust removal system, such as tungsten will replace the traditional stainless steel needle, has a good performance, durable, discharge effect is good, It can also be used for personal protection in addition to electrostatic ion fan ion gun, but also for silver and platinum electronic devices micro-beam plasma arc welding, stainless steel vacuum flask shell pulse micro-beam plasma arc welding and so on. An important condition of argon arc and plasma welding is ground grinding tungsten electrode, we can produce various specifications of grinding tungsten electrode, accurate grinding taper and Angle, to ensure the tungsten electrode shape size, grinding type: one end grinding point, or two ends grinding point.
Specifications of conventional grinding tungsten needle electrode:
1. Tungsten needle electrode diameter 0.5mm,0.7mm,1.0mm, 1.5mm, 1.6mm, 2.0mm 2.4mm, 3.2mm, 4.0mm, 4.8mm, 6.0mm.
2. Length of tungsten needle electrode: ≥9mm (length < 20mm, can only do one end grinding tip). Grinding tip Angle: 0-70°.
3. Tungsten content of tungsten needle electrode: W ≥ 99.95% and W ≥ 99.98%.
