Gold plating isn’t exclusive to those luxurious finishes – it’s also a highly functional surface treatment used in a variety of industries, such as electronics, aerospace and even medicine for certain devices.
Gold is highly conductive and provides great corrosion resistance and durability, making it far more versatile than simply adding some shine to something. However, it rarely works on its own.
Gold Alloys
Gold can be used as an alloy – especially common in jewellery, where carats are the most important measurement for gold’s value. It can also be used as a layer on top of another metal.
Copper is a great combination, as it has excellent conductivity and uniform consistency, making it easily applicable and elevating the properties of the product.
Although more difficult with nickel plating, the process of electroless nickel coating – provided by professionals such as poeton.co.uk/surface-treatments/plating/electroless-nickel-plating/ – can result in excellent uniformity on an otherwise unruly metal combination.
Applications
Gold is highly conductive and also very resistant to oxidisation, which is perfect for use in connectors, circuit boards or other electrical components that need to be highly reliable.
When paired with other metals, gold becomes stronger and more robust, enhancing solderability, adding wear resistance and even helping to meet environmental standards.
Nickel and gold are often used for printed circuit boards, aerospace connectors or even medical implants. Because these industries are highly dependent on reliable products, this combination needs to be airtight.
Gold adds a sheen and carries a current well, but the foundation is equally important. Keep that in mind when opting for gold plating.
