Tungsten wire mesh combines an open woven structure with a refractory-metal wire. Bright and black pure-tungsten wire options are available. Specify surface condition together with cleanliness, flatness and freedom from broken wires for the finished sheet.
Use the mesh in vacuum or a suitable protective atmosphere for furnace supports and heating-element constructions. Define working temperature, atmosphere, dwell time, mechanical load and electrical connections together. Tungsten’s melting point is a material property; the assembly’s operating temperature follows its thermal and mechanical design.
For equal-count square openings, geometric aperture a = 25.4/N − d in millimetres, where N is mesh per inch and d is wire diameter. A 100-mesh construction with 0.10 mm wire gives 0.154 mm (154 µm). Order by both mesh count and wire diameter, then define measured-opening tolerance.
The woven tungsten sheet provides a defined wire network. A furnace support, heater assembly or electromagnetic screen adds its own attachment and load path. The cutting drawing identifies warp direction, usable mesh area, edge treatment and clamped margin. Bright and black wire are specified as surface conditions together with the same declared tungsten-purity requirement.
14 mesh-count and wire-diameter combinations. The aperture column shows calculated square-opening geometry to three decimal places.
