Alodine (trade name) Aluminum and Zinc Die Cast; Aluminum Die Casting; Zinc Die Casting Paint base; Electrical conductivity; Anti-corrosion seal; Yellow

Chromate conversion coatings are also called chemical film coatings, or  Alodine or Irridite (trade names) coatings. They produce a very thin protective coating. Used mainly on aluminum or aluminum alloys, chemical conversion coating provides a protective layer against corrosion and can be used as a primer for paint.  Extra benefits accrue when the coating is sealed. This coating can be used for protection at the same time when low electrical resistance is needed.  

Erie Plating provides both hexavalent and trivalent chromate conversion. Trivalent chromate conversion coatings are nontoxic, RoHS-compliant, Nadcap-certified alternative to hexavalent chromate conversion coatings.

Aluminum anodizing Aluminum; Aluminum Alloys; 2024 Aluminum Alloy; 6062 Aluminum Alloy; 7075 Aluminum Alloy

Type II sulfuric anodizing places aluminum in a sulfuric bath and uses current to build up the aluminum oxide on the and near the metal surface.  This process provides corrosion and wear-resistance, and can be used as a base for paint.  The specific process will affect the coating thickness, while adding a seal can enhance the protective benefits.

Passivation is a process to provide a protective coating on metal to make it less reactive to its environment, preventing corrosion. For stainless steel, the problem is free iron on the metal surface. Passivation creates a protective oxide layer to shield the metal surface.

Specialty Sulfuric Acid Anodizing Aluminum; Aluminum Alloys; 2024 Aluminum Alloy; 6062 Aluminum Alloy; 7075 Aluminum Alloy

Type II sulfuric anodizing places aluminum in a sulfuric bath and uses current to build up the aluminum oxide on the and near the metal surface.  This process provides corrosion and wear-resistance, and can be used as a base for paint.  The specific process will affect the coating thickness, while adding a seal can enhance the protective benefits.

Stainless steel cadmium plating Castings; Forgings; Steel; Stainless Steel Clear chromate, silver appearance; Yellow chromate, yellow appearance; Olive drab chromate, olive drab appearance

Cadmium plating provides good protection against rust and corrosion in salt atmospheres and at low thickness, enhanced when it is sealed. It is resistant to mold and bacteria growth, with low electrical resistance and exceptional conductivity. It has favorable compatibility with aluminum to avoid galvanic corrosion.  It has natural lubricity (low-friction) properties.

Sulfamate Nickel Aluminum; Copper; Zinc; Carbon steel; Stainless steel Anti-corrosion; Electrical conductivity; Corrosion barrier; Paint masks

Nickel coatings can be very hard and durable, and are often used in applications requiring wear resistance. Nickel has a wide range of properties depending on how it is applied. The nickel layer can be decorative or "bright," provide corrosion resistance, wear resistance, or used to build up worn or undersized parts. It is often used as an undercoating.

Tin Plating Steel; Most common metals Matte dull finish

Barrel Tin finishes have the advantages of good adhesion, good ductility (ability to be deformed), an excellent lubricity (low-friction) surface finish, extended resistance to corrosion and rust, and  tough resistance to wear and temperature.

Trivalent Chromate Zinc Steel; Carbon Steel; Specialty Steel; Exotic Steel; Various Clear ROHS; Yellow ROHS; Seal with ROHS

Our Barrel Zinc products are RoHS (Restriction of Hazardous Substances) compliant. Hexavalent chromium is the concern with chromate conversion coatings on zinc. The RoHS Directive restricts hexavalent chromium, but does not restrict less hazardous trivalent chromium, which is used in our zinc processing. Zinc trivalent chromate coatings, also called zinc passivation coatings, provide an excellent, inexpensive, attractive finish and good corrosion resistance.

Tumble Burnishing

Tumble burnishing, also called tumble finishing, or just tumbling, is placing metal parts in a barrel with an abrasive media and rotating the barrel. Sometimes called barrel finishing, tumbling can smooth, deburr, clean and polish metal parts. The same process in nature produces "sea glass."

USG Anodizing Aluminum; Aluminum Alloys; 2024 Aluminum Alloy; 6062 Aluminum Alloy; 7075 Aluminum Alloy Critical Corrosion Protection

Type I Chromic Acid Anodizing passes an electrical flow (anodizing) through a chromic acid solution. This creates a thin aluminum oxide film that is non-reactive, a good primer base, and corrosion-resistant. This is a favored coating for parts undergoing high-stress, such as in the aerospace industry.

Vibratory Finishing

Vibaratory Finishing involves putting material, called the media, in a container with metal parts, and vibrating the container. The interaction of the material and metal parts deburrs, cleans, and smooths the metal parts.

X-Ray Thickness (NDT) Testing

X-ray thickness testing, or XRF, is a non-destructive way to test the thickness of a coating. When bombarded with X-rays, secondary rays (fluorescent rays) are emitted from the metal. The strength of these rays can determine the coating thickness.
