Gold Plating
Gold plating is an electrolytic process used mainly for its excellent electrical conductivity and corrosion resistance properties. This treatment is particularly appreciated in industrial applications requiring reliability and high performance, such as electronic components and electrical contacts.
Gold plating ensures low contact resistance, reducing wear and extending component life. Typically, an electrolytic nickel underlayer is used to prevent migration of the gold plating.
Technical Characteristics
Pure gold is deposited with a purity of 99.7%, with a hardness that can vary between 150 and 180 Vickers. Contact resistance ranges from 0.3 to 0.6 milli-ohms. Additionally, Supergalvanica's gold plating offers a shiny and uniform deposit appearance, ensuring high aesthetic and functional quality.

Frequently Asked Questions
5Electrolytic gold plating is a process that deposits a layer of 99.7% pure gold onto components. It is primarily used in the electronics sector, electrical contacts, and high-reliability connectors, where low contact resistance, excellent conductivity, and long-term corrosion resistance are required.
Yes, a nickel electrolytic substrate is generally used before gold plating. This prevents gold migration into the base metal, ensuring the stability and durability of the coating over time. The nickel + gold combination is one of the most common galvanic treatments for connectors.
Supergalvanica's gold deposit achieves a hardness between 150 and 180 Vickers, with a contact resistance between 0.3 and 0.6 milli-ohm. These characteristics guarantee excellent and lasting performance for critical industrial applications.
Yes, electrolytic gold plating maintains its conductivity and corrosion resistance properties even at high temperatures, unlike many other coatings. This makes it ideal for applications in thermally demanding environments such as high-power electrical contacts.
Durability depends on deposit thickness and operating conditions. Thanks to the nickel substrate that prevents migration and the high purity of the deposited gold (99.7%), connectors treated by Supergalvanica maintain optimal performance for extended periods even under intensive use conditions.
