Silver plating puts a thin layer of pure silver over another metal for electrical performance, thermal transfer, lubricity, or a brilliant decorative surface. It is the go-to for bus bars, contacts, and radio-frequency components — and for tableware and art.
Silver has the highest electrical and thermal conductivity of any element, which makes it the preferred finish wherever current or heat needs to move efficiently. It is also naturally lubricious and anti-galling, and it takes a brilliant polish for decorative work.
Typical applications
- Bus bars, contacts, and connectors where conductivity is critical
- Radio-frequency (RF) and microwave waveguides and components
- Bearings, gears, seals, and fasteners needing lubricity or anti-galling
- Aerospace, electric vehicle, and power-distribution hardware
- Decorative pieces, trophies, and restoration work
Properties & benefits
Peak conductivity
The highest electrical and thermal conductivity of any metal — the benchmark contact and bus-bar finish.
Natural lubricity
Resists galling and seizing on mating parts, especially at high temperature.
Brilliant finish
A polishable decorative surface with antimicrobial characteristics.
Practical thickness range
Typical deposits of 0.0001 inch to 0.0005 inch depending on use.
FAQ
Frequently asked questions
Silver tarnish (a sulfide film) has minimal effect on conductivity at contact pressure, so silver remains the best-performing contact finish for many applications. Anti-tarnish options are available for appearance-sensitive parts.
