Zinc Plating (RoHS Trivalent)

Zinc is one of the most common forms of electroplating. It gives corrosion protection to ferrous components which can be clear, yellow or black colored post treatments called chromates. The zinc electroplating process can be used to coat components for automotive, telecommunications, semiconductors, medical and government industries. It also provides an effective undercoat for paints when high corrosion performance is required.

Zinc Chromates (RoHS Trivalent)

Chromating is commonly performed on zinc plated parts to make them more durable. The chromate coating acts like a paint, protecting the zinc from white corrosion. Chromating can make the zinc plated parts several times more durable. It can be either hex or trivalent, and it can be clear, yellow, or black colored.

Anodize Type II & III (RoHS)

Anodizing is an electrolytic process used to increase the thickness of the natural layer already present on the aluminum surface. Anodizing increases the corrosion resistance and wear resistance and provides better adhesion for paint primers and glue than the bare metal. Anodic coating can also be used for a number of cosmetic effects. either type has a thick porous coating that can absorb dyes. Colors available: clear, black, blue, gold, red, green, grey, and others upon request.

Conversion Coatings on Aluminum (RoHS Trivalent)

Chemical Conversion Coating comes under different names like chem film, chromate, Iridite and alodine. A chemical conversion coat is a very thin protective coating of aluminum oxide. Although there are several kinds of chemical conversion coatings for aluminum, the most common are produced from a chromate. It can be it either hex, trivalent or chrome free. Chemical conversion coatings can be used for mild corrosion protection although they are normally used as an undercoating and base for organic finishes or adhesive bonding.

Electroless Nickel Plating (RoHS - Mid Phos.)

Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit. This plating technique is used to prevent corrosion and increase the wear resistance. Medium phosphorus has a high speed deposit rate and offers bright to semi-bright finishes options for cosmetic finish. This process is very stable, and is the most common type of electroless nickel applied.

Passivization of Stainless Steel

The passivization process removes "free iron" contamination left behind on the surface of the stainless steel from machining and fabricating. These contaminants are potential corrosion sites that result in premature corrosion and ultimately result in deterioration of the component if not removed. The passivization process facilitates the formation of a thin, transparent oxide film that protects the stainless steel from selective oxidation/corrosion. The passivization process cleans and protects the stainless steel substrate.

Chemical Polish for Copper and Brass

Chemical polish is a liquid acid solution used for chemically polishing copper and brass alloys.

Iridite 8P Bright Dip for Copper and Brass

Iridite 8P bright dip is a chromate conversion process that produces a variety of highly protective coatings on copper and brass alloys.
