Polishing of a metal surgace by making it anodic in an appropriate electrolyte.
Metal with an anodic coating, produced by an electrolytic oxidation process in which the metal is converted to a mainly oxide coating having protective, decorativr or functional properties.
Clear Anodized Metal
Metal with a substantially colorless, translucent anodic oxidation coating.
Color Anodized Metal
Anodized metak colored either during anodizing or bybsubsequent coloring processes
Integral color anodized metal
Metal that has been anodized using an appropriate electrolyte which produces a colored coating during the anodizing process itself.
Electrolytically Colored Anodized Metal
Metal with anodic oxidation coating that has been colored by the eletrolytic deposition of a metal oxide into the pore structure.
Dyed Anodized Metal

Combination Color anodized Metal
Metal with an anodic oxidation coating that is colored by electrolytic coloringor produced by integral color anodizing followed by absorption dyeing.
Interference Color Anodized Metal
Metal with an anodic oxidation coating colored by means of optical interference effects.
Bright Anodized Metal
Anodized metal with high specular reflectance as the primary characteristics.
Anodizing where protection against corrosion or wear is the primary characteristic and appearance is secondary or of no importance.
Anodizing where a decorative finish with a uniform or a aesthetically pleasing appearance is the primary characteristic.
Anodizing to produce an architectural finish to be used in permanent, exterior and static situations where both appearance and long life are important.
Hard Anodized Metal
Anodized metal on which the anodix oxidation coatinf has been produced with weae and/or abrasion resistance as the primary characteristics.
Treatment of anodic oxidation coatings on metal tonreduce porosity and the absorption capacity of the coating by hydrothermal process carried out after anodizing.
Treatment of anodic oxidation coatings on metal to plug the pores and reduce the absorption caapcity of the coating by chemical processes carried out at low temperatures after anodizing.
The part of the product covered or to be covered by the coating and for which the coating is essential for serviceability and/or appearance.
This process uses a colored powder that is given a positive electric charge. The metal part is given a negative electric charge. Then the powder is sprayed onto the metal, and the electrostatic charhe allows the powder to stick to the metal part. Once the powder is attached to the metal, the part is baked into a kiln to fuse the powder to the metal surface. Then, the color is permanently attached. The finished surfave will not corrode from the elements, which makes them ideal for exterior applications.
raising, molding or carving a surface design relief
To carve, cut designs
The process of using strong acid or mordant to cut into the unprotected parts of the metal surface to create a design.
A technique used to work metal into a raised design or pattern by sinking the front surface, used in combination with repousse which is the opposite design is raised through the reversed side.
Heating metal to restore it to its softest possible working state.
Treating steel to improve its corrosion-resistance. The metal is heated to create an oxide-skin, and then quenched in oil.
Production of metal shapes by pouring molten metal into moulds
Forcing malleable materials through holes to produce bars, sections or tubes.
Shaping hot metal by hammering
Producing maximum hardness in high carbon steel by heating it to bright cherry red, then quenching it in water or brine. This process makes metal brittle and is usually followed by tempering.
Forming sheet metal into shape with a press tool.
A process in which a fast revolving sheet of ductile metal is forced over a wood or metal form.
Removing some of the brittleness from steel after it has been hardened.
pulling ductile metals through holes in a plate, to reduce their cross-sectional areas
