Galvanic gold
With its good electrical conductivity, galvanic gold, or hard gold, is useful for contacting due to the low transition resistance. In addition, the treatment is corrosion-protective and has a hardness of approx. 160 HV.
Galvanic gold
Gold can basically be divided into two categories, cosmetic gold and functional gold.
We offer both types, but mainly focus on functional gold.
Gold has good electrical properties, which is used for switches and connectors found in most electronic products.
At Chem-Tec Plating, we offer:
- Hard gold
- Soft gold
- Antique gold
While hard gold and soft gold are mostly used for electronics, antique gold is used more often for decorative purposes. We offer all three types. They all consist of 24 carat gold.
Typical layer thickness:
0.1-2.5 µm.
Appearance:
Hard gold looks like gold from the goldsmith and has a shiny surface, depending on the starting material.
Antique gold has a lighter shade than hard gold and may used if you want items that should look like brass.
Application:
Gold is suitable for electronic components such as switches, connectors, springs, circuit boards, etc., for decorative purposes or as an alternative to brass products.
References:
Galvanized nickel/gold is also called hard gold, as the gold is alloyed with approx. 0.2 % nickel or cobalt.
Combination coating:
Typically, one would have an underlying coating of nickel before adding gold.
The nickel can be either matte or shiny, depending on how you want the end result to look.
With an underlying coating of nickel, it is also possible to coat steel, stainless steel, aluminium and tin bronze.
Suitability:
Gold is highly suitable for contacting as it reduces transition resistance and heat development in electrical connections.
Setup Method:
Fixtures or drums.
Dimensions:
L x W x D 500mm x 250mm x 600mm
For other sizes, please contact us.
Series size:
Our process plant is built in such a way that we can handle series sizes at all levels, from a single item to many millions.
