Sulfuric Acid Anodize Definition: Sulfuric acid anodizing is a conversion on aluminum which changes the surface to an aluminum oxide film that can range from (.0001″) – (.001″) thick. This oxide coating gives the aluminum a greater resistance to abrasion, protects from corrosion, and provides excellent thermal and electrical insulation. The aluminum oxide builds up on the surface and penetrates into the material an equal amount. Sulfuric acid anodize films are naturally porous which makes them great for absorbing colored dyes which can be later sealed with a PTFE coating to further protect against abrasion and bleaching effects caused by sunlight.
Conversion Coating (Chem-Film) Definition: Chromate conversion, also known as chemical film, alodine or iridite, offers increased corrosion protection on aluminum. It is inexpensive, electrically conductive and is often used as a pre-treatment for paint and adhesives. Chromate can be used as a standalone finish or as a post treatment over other metal plating finishes.

Powder Coat Definition: Powder coating is a type of coating that is applied electro-statically, using a free-flowing, dry powder. After application, it is cured under heat to provide a hard finish that is tougher than conventional paint. It is commonly used by the medical, commercial, auto, and defense industries. The toughness of the finished product allows for indoor and outdoor applications; even in the most extreme of conditions. It is known as a “green” product, emitting zero VOC’s.

Copper Definition: Copper plating is a electrolytically deposited metal finish that has functional and decorative characteristics. Decorative finishes are often lacquered after plating due to the fact copper readily oxides. Functional copper is used because of its excellent electrical and thermal conductivity. Copper is also used as a base layer or underplating. The benefits of underplating are improvements in final finish, adhesion and corrosion resistance. Mil-C-14550 Classifications Class 0 – 0.

Bright dip Definition: Bright dip is an immersion acid based application used to protect and clean copper and brass. The finish can remove scale, oxide and tarnished surfaces leaving a uniform natural color. The material will readily oxide and JMD recommends using a conversion coating to further protect the material from corroding. Available Processes Hand-Line Note: Bright Dip is a RoHS compliant metal finish Electropolish Definition: Electropolish is a process that removes material from the surface of stainless steel which creates a smooth, bright, mirror-like finish.
