As for tungsten, also tungsten-rhenium is sometime gold coated for reasons such as corrosion and soldering to other metals.
Standard gold coat thickness for wires < 50 microns is 3-5% by weight. For wire dimensions > 50 microns the coat thickness is 0,5 micron.
Upon request we also manufacture wire with non standard coat thickness.
Examples of applications; Printing, Antennas and Technical Research
