Product Description:

Tungsten Mesh is resistant to oxidation attack and corrosion in acidic and alkaline media. It is used in the elevated temperature filtration applications. Tungsten Mesh offers excellent high temperature mechanical characteristics and smallest coefficient of thermal expansion among all metals. It has supreme thermal creeping resistance and maximum service temperature up to 3400oC. Tungsten mesh is extremely durable. The mesh surface is flat, clean and flawless. Therefore it is a vital filter and screening material for mechanical, electrical, vacuum equipment, heating and other special applications.

Tungsten Mesh Applications:

Chemical industries, acid production, scientific research labs and universities,  filter, vacuum apparatus, hydrogen production, fire hazard security and heat shielding

Tungsten mesh properties:

  1. Tungsten mesh offers the highest furnace service temperature about 3000oC with suitable optical heat transfer performance for specific temperature uniformity.
  2. Large surface area decreases the watt density resulting in enhanced element service life.
  3. Mild wire tear will not affect the mesh service life in any case.
  4. Tungsten mesh is produced in the specific sizes, shapes and styles to fit any type of vacuum furnace
  5. The mesh element can perform at the minimum temperature in correspondence to the service temperature limit.
  6. As the thermal stress are unavoidable during heating operations in the high temperature furnaces, an inherent flexibility of tungsten mesh and weave designs, handle the stress more significantly.
  7. Tungsten metal mesh sustains dimensional stability during the frequent heat cycling. As the mesh has large radiating area, its surface life is considerably increased by decreasing the surface watt loading on the heating elements.

Advanced production, consistently high quality and assurance of prolong reliability

 Tungsten mesh widely discards the mechanical and thermal stress hence provides significantly enhanced element life. While producing the Tungsten wire mesh, each wire coil (warp or weft wire) is woven together with second coil to produce regular mesh network over the complete width and length of element that offers incomparable thermal service. As the diameter of both warp and weft wires are closely controlled, accuracy in the mesh production is assured throughout the element. We can control wire diameter, pitch and height of bends as required to produce the desired woven mesh design. The wires pass through each other alternatively to develop a wire cloth by secured interlocking.

Tungsten mesh has extensive applications in the construction and engineering industries because of its good durability and strength. It is used in protection from fire hazards as it has very high melting point. Tungsten wire mesh has the greater physical stability and print repeatability as compare to traditional steel mesh.

Tungsten mesh is produced in to a variety of weaving styles. The final product undergoes rigorous quality control test to ensure that it is produced to the best standards. It is offered in both cylindrical and flat panels. We can also deliver cut to size service and produce non-standard mesh sizes to order.
