COATINGS

Most of our Contact Elements are silver-plated. Depending on your requirements, we offer a wide range of coatings. Please choose your coating using the BAUMANN inquiry form.


Silver
Silver is the best conductive element and applied broadly in electronics and electrical applications.

Silver is used whenever excellent conductivity and high abrasion resistance are necessary.


Gold
Gold plating is a very common surface treatment in electronics to increase contact behavior and corrosion resistance; no other coating is as resistant towards corrosion with good connectivity at the same time. Gold-plated material is additionally well solderable.


Zinc

Galvanized zinc is smoother than hot-dip zinc layers and looks similar to a chrome-plated surface. Zinc provides excellent protection against corrosion. With subsequent passivation steps, zinc coatings can be provided in blue, yellow, black and olive.


Copper

Copper as the second-best conductive material can be applied to improve conductivity or protect the base material from corrosion. Copper layers can also be applied to improve adhesion between the base material and final coating.


Tin
Tin has a decorative, silver-white appearance, and is well solderable, ductile and corrosion-resistant. Due to its purity, non-toxicity and neutral taste, it is applied broadly in the food industry.

Tin also improves connectivity due to its softness.


Nickel
Nickel is one of the most important electrodeposited metals due to its outstanding chemical and mechanical properties. Nickel-plated surfaces are high in gloss, and have increased corrosion resistance and excellent ductility (ability to smooth out surfaces).
