Gold Plated Tungsten 

For some applications tungsten wire has to be plated to meet special requirements. This may for instance be to protect the wire from corrosion, to solder it together to other metals or to reduce the secondary emission of electrons.

Luma gold plated tungsten wire has as standard a coat thickness corresponding to 4+1 % of the wire weight up to wire diameters of 50 microns. For wires above 50 microns in diameter the coat thickness is 0,5 micron.

Wire qualities, gold plated tungsten
821
Is the wire of 820 standard quality, which has passed the requisite tests to meet the demands for wire of a higher standard below Ø 50 microns i.e. virtually free from traces of cracks and splits.
