Yes, regularly. This is a specialty for INTA Technologies Corporation and we have been using the same process for many years.
Platinum plating is very popular for many reasons. Platinum does not oxidize or tarnish. Platinum plating is used for catalytic converters (automotive), surgical and medical equipment, and low voltage, low current applications. A thin deposit of platinum protects the substrate very well and has made platinum very popular for a coating selection. Platinum plating is used for anodes and for protecting substrates from harsh or chemical environments.
No, electrolytic only.
Platinum plating is one of the more expensive coating options. Use platinum for high-end applications and corrosive environments. Platinum is more expensive than gold but less than rhodium. Each project is unique. For an exact price quote please contact INTA Technologies.

Standard lead time is five (5) days. Same day or expedite service available in many cases for an additional charge.
The two coatings are used for different applications. Platinum plating is especially important in the electrode manufacturing segment and gold would not be an adequate alternative. Platinum is more costly than gold, but often a thin coating of platinum will suffice – making up for the price difference between platinum and gold. In most cases platinum plating is good for high temperature applications but is more costly than gold plating.
In general, our maximum size for platinum plating is 12” length and 6” OD although exceptions occur.

In many cases platinum plating is necessary and there is not a less expensive alternative. In other cases, however, alternatives exist. For high temperature applications, platinum and rhodium are very popular. For further analysis send your drawings and requirements to:
