Platinum Plating
The most durable white finish we offer.
Platinum plating deposits a bright, silvery-white layer that never tarnishes, resists nearly every acid and chemical, and stands up to wear that would dull softer metals. When a piece has to look flawless for decades or survive a punishing environment, platinum is the answer.
The process electro-chemically deposits a thin, uniform layer of pure platinum onto a base metal. Because platinum is one of the densest and most chemically stable metals known, the finish is exceptionally hard, corrosion-proof, and biocompatible. It carries a naturally white color that stays bright without the periodic re-plating that white gold requires.
Properties & Benefits
Permanent white finish
Bright, permanent white that will not tarnish or oxidize — no periodic renewal required.
Chemical resistance
Outstanding resistance to acids, chlorine, and industrial chemicals.
Hardness and heat tolerance
Very high hardness and wear resistance for a decorative metal, with a melting point near 3,215°F, so it holds up under heat.
Biocompatible
Hypoallergenic and biocompatible — safe for skin contact and medical use.
Best For
- Luxury jewelry and watch components that must stay bright for life
- Medical and dental parts where biocompatibility is required
- Electrical contacts and sensors exposed to corrosive conditions
- Laboratory and chemical-handling components
- Any part where a permanent, maintenance-free white finish matters
Specifications
Platinum is typically applied in thin, controlled deposits because the metal is among the most expensive we plate. For decorative work, thickness is usually in the range of 0.00005 inch to 0.0002 inch, tuned to the application. Heavier builds are available for functional and corrosion-critical parts. A nickel or palladium underplate is often used to improve adhesion and coverage.
Pricing
Platinum work starts at our standard $500 minimum. Because platinum spot pricing drives most of the cost on larger surface areas, we quote each platinum job firm and per project after a photo review rather than at a flat per-square-inch rate. See pricing details.
Frequently Asked Questions
Both are bright white and corrosion-proof. Rhodium is more reflective and is applied as an ultra-thin flash; platinum can be built thicker, is more ductile, and is better suited to functional and heavier-wear applications.
