Tungsten is the most useful material used in vacuum evaporation technique, due to its special properties and cost factor.
Use tungsten wire for evaporation in high vacuum evaporation systems made by Cressington, Denton, Edwards, Jeol, Ladd or others. Thin wire is offered for additional deposition/evaporation/filament applications. This vacuum grade, wire comes cleaned and coiled in diameters of 0.13mm, 0.51mm, 0.6mm and 0.76mm.
