Gold Plating
General Details and Specification of gold plated Finishes
Yellow to orange color depending on proprietary process used. Will range from matte to bright finish depending on basis metal. Good corrosion resistance and has high tarnish resistance. Provides a low contact resistance, and is a good conductor. Has excellent solderability. Unless otherwise specified, an intermediate nickel plate is required on copper base alloys or copper plated surfaces prior to the gold plating.
Benefits of gold plating
- Excellent electrical and thermal conductivity
- Offers exceptional solderability
- Superb reflector of infrared radiation
- Does not oxidize
- Chemically inert under normal conditions
