Tungsten wire ensures sharp cuts of very thin and very flat walled details. It like molybdenum wire is also used on sensitive products, and prevent zinc and copper residues on surfaces. Cost is high and is not preferred except for special uses. Electrodes can be produced from various precious materials including fine silver, silver tungsten, and copper-tungsten alloy.

Tungsten wire is made of doped powders. Powders are combined under high pressure and are sintered at high temperature and processed by rolling and mixing into heavy rods suitable for drawing. We produce tungsten wire and tungsten rods according to quality standards.


  • Tungsten is preferred in high-temperature applications due to its high melting point (3410 ° C).
  • Heat and electrical conductivity are high.
  • Thermal expansion and vapor pressure coefficient at high temperatures are low.
  • It is capable of absorbing highly effective radiation and X-rays.
  • It is produced with a tolerance of ± 2 mm.
  • Special wires can be produced according to the special requirements of the customers.
Place Holder



They are packed with dust, shock and oxidation-resistant materials to protect our wire rollers from transport damage and pollution.


The loose end of the wire must be properly fixed. Improper handling and storage of the pulley cause distortion and wire breakage.


Half wire reels should be stored in their original packaging.
