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. Mil-C-5541 or Mil-DTL-5541 or Mil-DTL-81706 Classifications Type I-Compositions containing hexavalent chromium Type II-Compositions containing no hexavalent chromium Class 1A-For maximum protection against corrosion, painted or unpainted Class 3-For protection against corrosion where low electrical resistance is required ASTM B449-93 (re-approved 2015) Classifications KEY: Class, Appearance, Coating mass per unit area g/m2, corrosion protection
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.

Electroless Nickel Definition: Definition Electroless Nickel Plating is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus without an external current. This process produces coatings of uniform thickness which is beneficial when plating irregularly shaped objects, holes, recesses, internal surfaces, valves or threaded holes. Electroless nickel is more corrosion resistant then traditional electrolytic nickel. Mil-C-26074 Classifications Class 1 – As plated with no subsequent heat treatment

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.
