More than Bling: Gold as Technological Material

Gold is a truly unique material that has a lot more to offer than its good looks.

  1. Pure gold is the most ductile metal. It’s even possible to craft gold wires that are as thin as one atomic layer.

  2. It’s the noblest of all metals and only oxidizes under very specific conditions.

  3. It has great electric conductivity (4,5 x 107 S/m) and only gets overshadowed by copper (5,8 x 107 S/m) and silver (6,1 x 107 S/m).

  4. It’s non-toxic and non-irritating.

  5. Gold has excellent reflective properties and works well against electromagnetic radiation (infrared as well as radiowaves and visible light).

  6. It’s very dense (19,2 g/cm³).


Knowing all these facts it’s not surprising that gold finds a lot of applications outside of decorative electroplating.

In most cases you won’t find pure 24 K gold in galvanic layers (although it is possible). To make the gold layer brighter, harder and more even, other substances (like Cobalt) get deposited as well.

Gold as Bonding layer
Plating stainless steels (and some other metals and metal alloys as well) is usually achieved by using a bonding layer of Nickel before applying the desired metal layer.

However, nickel is ferromagnetic and therefore unusable for certain applicances like measurement and high frequency technology. It also gets increasingly avoided by medicinal technology and the jewelry industry because of its allergenic properties. In cases like these we offer a bonding layer of gold.
Gold with its pretty yellow color also differenciates better from the stainless steel surface than most other metals, making it easier to spot flaws in the bonding layer.

Gold in Space Travel
Because of its reflective abilities and non oxidative properties gold is a most desired material in space travel. Astronaut’s visors, for example, are coated with a thin gold layer that protects them from cosmic radiation without producing a glare.
