Silver Plating Services
Silver is commonly known as a precious and decorative metal, but it also has desirable properties for metal finishing and industrial manufacturing applications. First and foremost, as a noble metal, silver resists oxidation (even at high temperatures). Silver also provides excellent solderability, ductility, conductivity, corrosion resistance, and lubricity at a relatively inexpensive cost compared to several other metal plating options. With its brilliant white luster, it can also serve cosmetic purposes in matte, semi-bright, or bright finishes. Silver has the highest optical reflectivity in the visible range, making it ideal for reflective applications such as mirrors.
A silver finish is a much more cost-efficient alternative to gold plating in many applications, while producing similar overall results. The most notable weakness, by comparison, is silver’s ability to tarnish in suboptimal conditions. However, it’s also possible to finish silver plating with a chromate post-treatment that improves its tarnish resistance.
Silver plating can be found in applications throughout many industries, such as aerospace and defense, electronics, consumer/home goods, automotive, medical, power generation, and musical instruments. It’s a highly versatile metal with a long list of desirable traits and is often preferred over similar but much pricier metals such as gold. One of the more common uses of silver in an industrial context is as anti-gall on fastener threads, static seals, and bushings, where it also provides temperature resistance and corrosion protection.
The great solderability of silver suits it well to small parts such as kitchen utensils and cutlery (“silverware”), and its high reflectivity is a key property that’s been relied upon in the photography and mirror-making industries for many years. Due to the extremely low electrical resistance exhibited by this metal, it’s also found a home in the renewable energy sector. Silver is seen as a sustainable and affordable metal plating option than palladium or gold for solar panel, battery, and other clean energy components that require conductive properties.
Medical devices may incorporate silver-plated components due to the sterile nature of silver, which is an excellent antibacterial choice for hospital environments. Its classification as a noble metal speaks to its durability, as well. Silver is highly resistant to corrosion and has a very high melting point, making it a long-lasting go-to metal for demanding industries such as aerospace.
- Superior ductility and wear resistance
- Great durability
- Excellent solderability
- Corrosion resistant coating
- Excellent high-temperature lubricity
- Withstands very high temperatures
- High thermal and electrical conductivity
- Lightweight for a metal of this durability
- Delivers its best qualities even in an extremely thin plate (as low as 0.0003 inches)
- ASTM B 700
- AMS 2412
- AMS 2410
- AMS 2411
- SPOP 23 PW
- Tarnishes easily
- Solderability decreases with age
- Not a hard protective layer; silver is soft and malleable
- Vulnerable to sulfur, which creates tarnishing
Although silver can tarnish, it’s possible to apply anti-tarnish chromate and non-chromate coatings that improve tarnish resistance and slow the process. If tarnishing is a concern, it’s also best to use silver in applications that do not involve exposure to sulfur — the main cause of this reaction. Products finished with a silver plate can be packaged in silver-saver protective papers or other non-sulfur containing options to help preserve their sheen.
