Gold Plating

Galtek provides bright, semi-bright (matt), smooth, crack-free and uniform gold plating at 99.7% (hard gold) and 99.9% (fine gold) purity, up to 10 µm thick. The deposits are hard, improving wear resistance and service life.

Hard gold is used on electrical contacts, terminals, switches, connector pins, interconnect pins and spring contacts to resist wear from repeated friction. Fine gold is common in soldering, high-temperature and high-corrosion applications; being inert (it does not rust, tarnish or dull), non-toxic and biocompatible, it is widely used in medical and dental applications.

We plate in line with international standards such as ASTM B488-01, MIL-G-45204D and AMS 2422E, choosing the standard to match the customer’s requirement. Critical parameters such as thickness, conductivity, corrosion resistance and mechanical strength are closely controlled.
