Tungsten wire mesh
Specifications:
Tungsten mesh has characteristics of high hardness, high melting point, is not erosion in the air at room temperature , mainly used for the manufacture of steel filament and high-speed cutting, hard mold, also used in optical instruments, chemical equipment.
Tungsten mesh grades: W-1, W-2, WAL-1, WAL-2.
The physical properties of tungsten wire mesh: the melting point of 3410 ± 20 ℃
Density 19.35 g / cm3
Chemical properties of tungsten mesh: high melting point, low vapor pressure, the evaporation rate is smaller, chemically very stable at room temperature without reaction with air and water, without heating, any concentration of hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric tungsten acid, and aqua regia does not work
Tungsten wire mesh Standard: GB / T4181-1997, GB4187-84.
Welding properties of tungsten wire mesh: with copper and other metals welding, using a variety of welding processes, can achieve satisfactory results.
Tungsten mesh surface treatment process: at high temperature parts can effectively protect the coating
