the ideal platinum / palladium plating
Platinum and palladium platings are valued for their outstanding chemical resistance and noble appearance. They are ideal for jewellery and high-quality consumer goods.
Platinum offers excellent protection against corrosion and wear and is used as a catalyst in a wide range of technical applications, while palladium offers high ductility and good solderability. In electronics they are used for contacts and printed circuit boards, where reliability matters.
Platinum (Pt) as a catalyst
In chemistry, platinum is something of a "matchmaking genius": it brings reaction partners together by drastically lowering the activation energy of a reaction without itself being consumed.
Adsorption: gas molecules (such as hydrogen or oxygen) attach to the platinum surface. The bonds within these molecules are weakened or even broken apart entirely.
Reaction: the now "activated" atoms can form new bonds with other reaction partners on the surface much more easily.
Desorption: as soon as the new product has formed, it detaches from the surface and frees up the space for the next molecules.
This capacity for heterogeneous catalysis makes platinum indispensable for exhaust-gas cleaning in cars (conversion of CO into CO₂) as well as for fuel-cell technology, where it is what enables the efficient reaction of hydrogen and oxygen in the first place.
Palladium-nickel (PdNi)
Palladium-nickel platings offer an excellent balance between hardness, corrosion resistance and cost-efficiency. They impress with a homogeneous layer structure and high microhardness, allowing us to achieve a significant extension of service life compared with pure nickel or gold platings while at the same time reducing the use of precious metals. They are frequently used in connectors, switches and as a durable top layer on premium consumer goods.
Palladium-tin (PdSn)
Palladium-tin platings combine very good corrosion resistance with excellent solderability and a fine, uniform surface structure. Thanks to their durability and bright appearance, they are found on decorative surfaces such as in the eyewear industry or on exclusive watch cases. In electronics they are a proven alternative to pure gold and impress with consistent electrical properties and high long-term stability.

FAQ
Frequently asked questions about platinum & palladium plating
Is a palladium-nickel layer solderable and suitable for plug contacts?
Yes. Palladium-nickel provides reliable contact behaviour and works well for pluggable connections and contact surfaces. For solderability we combine it with a suitable top metal where needed and match the build-up to your assembly.
Which base materials can you plate with platinum and palladium?
We plate both self-manufactured and supplied parts on common metal substrates. A suitable base layer ensures adhesion and contact reliability even on demanding geometries.
What does electroplated platinum or palladium plating cost?
The price depends on part geometry, layer thickness, quantity and precious-metal input. We calculate per project and provide a concrete quote on request.
