Al chromating yellow (Alodine)

General Al chromating is a chemical process and produces light yellow iridescent to brass yellow chromating layers (containing CrVI) on aluminum and its alloys. The layer is <1 µm.

Al-Passivation colorless

General Al passivation is a chemical process and creates a colorless, slightly iridescent layer. This process of surface coating is chromium VI-free and colorless. The colorless passivation (Surtec 650) is RoHS and REACH compliant.

Burnishing of steel

General Burnishing creates a decorative brownish to black oxide layer, which acts as a weak protective layer on iron-containing surfaces to reduce corrosion. The non-permanent corrosion protection of a burnished steel part is optimized by treatment with oils.

Chemical nickel plating, currentless

This is a deposition of nickel and phosphorus (NiP), this is done without current. (Autocatalytic separation). Chemical nickel plating produces contour-true coatings without edge build-up, which means that even geometrically complex components can be coated well. The process also offers excellent corrosion protection properties and wear protection of the surfaces thanks to its higher abrasion resistance.

Chrome plating

General Chrome-plated products offer high aesthetics thanks to the blue and white glossy surface. Highly polished surfaces are strong reflectors.

Copper / copper

The galvanic copper plating offers aesthetics and at the same time protection against corrosion. The galvanic copper layers are often used as a basis for improving corrosion resistance and as an intermediate layer before nickel plating, chrome plating, silver plating and gold plating. The good polishability of the copper forms a good basis for use in the decorative area.

Electroplated nickel, nickel plated with electricity

General Electroplated nickel layers are silvery light with a slight yellow tinge. The primary use is the decorative coating, since matt or high-gloss surfaces can be created here.


General In the anodizing process, an anodic oxidation layer (protective layer) is created on aluminum by an electrochemical process. The converted layer is wear-resistant and protects against corrosion. The aluminum oxide layer is a good insulator in terms of continuity and the layer can also be colored.

Galvanizing – Blue, Black, Yellow and Olive

General Galvanizing is a surface process that is primarily chosen for its anti-corrosion properties. Galvanizing is an inexpensive and decorative surface process. Depending on the desired look and property, the zinc layer can be passivated / chromated. The following passivations can also be offered in compliance with RoHS: colorless, blue, yellow and black.

Gild / Gold plating

General Gold plating is not only used in the jewelry industry but also in the technical area. The excellent conductivity makes the gold plating of components so important for the electrical engineering industry. Gold-plated elements can be soldered very well. The decorative and resistant, yet valuable surface is crucial in the decorative jewelry industry.


General Our silver surfaces offer excellent electrical conductivity and thermal conductivity as well as an aesthetic, decorative shine.

Stainless steel passivation

General Passivating stainless steel creates a protective layer and, at the same time, foreign iron or mixed iron crystals are removed from the surface, which increases corrosion protection.

Tinning (galvanic)

General Tin is a silver colored, shiny metal that is easy to stretch. The galvanic tinning offers a very good protection against corrosion, tin is also food safe and can be soldered very well and is very conductive.

Zinc phosphating

General The primary task of a phosphate layer with zinc phosphates on steel is corrosion protection. To ensure protection, a varnishing is carried out, or the workpieces are then greased.
