the right silver plating
There are many reasons to coat objects with silver. First and foremost, of course, the noble appearance and high intrinsic value. Silver is a hallmark of class, which is why silver platings are particularly suited to luxury items and jewellery.
Silver also offers materials-engineering advantages, for example silver-coated items are very durable. In electrical engineering, the low contact resistance and outstanding solderability are highly valued. That is why we plate electronic contacts and connectors with silver in our modern electroplating facility.
Silver and its oligodynamic effect
The oligodynamic effect describes the antimicrobial property of metal ions even in the smallest concentrations. Silver is regarded as the preferred material for surface coatings due to its high biocompatibility and strong broad-spectrum action. The effect is based on the continuous release of positively charged silver ions (Ag+) in moist environments, which damage the bacterial cell wall, block essential enzymes and thereby disrupt the microorganisms' energy production.
Pure silver layers
Pure silver layers are often applied as a final finish on silver alloys to reduce the tarnishing behaviour classically known from silver cutlery. Silver alloys such as Ag 925 with around 7.5% copper or Ag 500 with around 50% copper are frequently used. The copper content increases the usability of the items through a significant rise in hardness, but also leads to poorer tarnishing behaviour. Our pure silver layers substantially reduce this tarnishing.
Silver and electrical conductivity
Among all chemical elements, silver is the champion of electricity. Under standard conditions it has the highest electrical conductivity of all metals, ahead of even copper and gold. Silver's high conductivity results from its electron configuration: the single electron in its outer s-shell is highly mobile and undergoes only slight scattering by the atomic cores in the crystal lattice. We silver-plate electrical and electronic components for signal and power transmission.
The benefits of galvanic
silver plating
Our silver plating stands out for its high purity and conductivity.
The silver is applied precisely and evenly, ideal for electronic components and decorative elements.
Silver-plated surfaces offer excellent protection against corrosion and improve electrical conductivity.
By varying the layer thickness, we tailor the coating optimally to your needs.

Silver plating –
as a contract service or in-house
On the one hand we plate parts produced in-house with silver, on the other hand we coat products delivered by our customers. This applies both to luxury goods such as jewellery and to technical components such as electrical contacts.
SURPRO carries out all platings with the utmost care and using the latest technical methods. We can coat both large series and small batches.

FAQ
Frequently asked questions about silver plating
Which silver layer thickness makes sense?
It depends on the application: signal transmission often needs thinner layers, while high currents or wear loading call for heavier deposits. We recommend the right layer thickness for your use case.
Can silver be deposited on copper and non-ferrous metals?
Yes, silver plates well on copper and non-ferrous metal parts. Where needed we apply a suitable base layer to secure adhesion and long-term behaviour.
How is an even silver layer achieved on complex parts?
Through a matched process and suitable fixturing we achieve even coverage even on demanding geometries. We tailor the exact execution to your components.
