No longer chrome-VI

After many years of use of hexavalent

chromium for galvanic coating as corrosion

protection, legislative authorities and also the

market call for a change.

Due to new guidelines the elimination of

chrome-VI will become a matter of course for

the automobile industry as well as machinery

construction.

Yellow chromating will therefore step-by-step

be replaced by zinc-nickel coating.

Yellow chromating has granted process

reliability to the user over years, also within the

field of central lubrication. The A3C surface

had excellent corrosion protective properties

against white rust and red rust.

Improved corrosion protection by ZnNi

Zinc-nickel coating does not only considerably

increase the corrosion resistance but is also

characterized by highest environmental

compatibility and a high-quality appearance.

Surfaces coated with zinc-nickel prove to have

a significantly higher resistance against

corrosion than the previous solution with A3C.

Red rust has only developed after 720 h of

salt-spray testing according to DIN EN ISO 9227.

BEKA puts the focus on ZnNi

As this new coating offers so many advantages,

we deliver all relevant components and parts*

with it, like e.g. lubricant distributors, fittings,

fixtures and bases, pump elements and others.

* Due to technical reasons zinc flake coatings are used as

an alternative for small parts. However, those also have a

corrosion resistance of 720h.

Progressive distributor type LX-4 with ZnNi-coating

Advantages of ZnNi coating:

High corrosion resistance

Free of hexavalent chromium

The zinc-nickel base layer is much more resistant to corrosion than zinc

White rust only occurs as a slight grey coating

Provably better corrosion resistance compared to previous A3C standard

Already well-proven standard for the European automobile industry
