ALL ABOUT ANODIZING

Anodizing is a process for finishing aluminum alloys that uses electrolytic oxidation of the aluminum surface to produce a protective oxide coating.u00a0 The anodic coating consists of hydrated aluminum oxide and is considered resistant to corrosion and abrasion.u00a0 Coatings are 0.1 to 1.0 mil thick and are essentially transparent, although they may be colored.u00a0 Unlike most other finishes, anodizing preserves the natural luster, texture, and beauty of the metal itself.u00a0 The anodized coating is hard, durable, will never peel, and, under normal conditions, will never wear through.<br>

  2. ALL ABOUT ANODIZING • WHAT IS ANODIZING? • Anodizing is a process for finishing aluminum alloys that uses electrolytic oxidation of the aluminum surface to produce a protective oxide coating.  The anodic coating consists of hydrated aluminum oxide and is considered resistant to corrosion and abrasion.  Coatings are 0.1 to 1.0 mil thick and are essentially transparent, although they may be colored.  Unlike most other finishes, anodizing preserves the natural luster, texture, and beauty of the metal itself.  The anodized coating is hard, durable, will never peel, and, under normal conditions, will never wear through.

  3. WHAT IS THE PURPOSE OF ANODIZING? • The purpose of anodizing is to form a layer of aluminum oxide that will protect the aluminum beneath it.  The aluminum oxide layer has much higher corrosion and abrasion resistance than aluminum.  There are some types of anodizing that produce a porous oxide layer that can be colored with organic dyes or metallic pigments giving the aluminum a decorative and protective finish.  In short, the main purposes for anodizing are corrosion resistance, abrasion/wear resistance, and cosmetics.

  4. IS ANODIZING SAFE? • When it comes to coatings, anodizing is a safe and environmentally friendly technology, as clean a process as is available today.  Anodizing is an acceleration of a natural oxidation process.  It does not produce harmful or dangerous by-products, and will not damage human health or the environment.  Other benefits include: • The finish is non toxic • It is heat-resistant to 1,221°F(the melting point of aluminium) • Anodizing uses simple water based chemicals that can be treated easily and that release no harmful by products

  5. The liquid by-product can be recycled and returned to the process • The solid by-product can be separated for other such as aluminium, manufacturing, baking powderetc • The primary by-product are harmless

  6. HOW DO I DETERMINE THE PROPER ANODIZING FINISH TO USE? • This is determined by the final use of the part and the physical specifications and characteristics needed such as color, hardness, indoor or outdoor use, resistance to high UV levels and fading, and resistance to corrosion.

  7. WHAT ALLOYS ARE RECOMMENDED FOR ANODIZING? • Most aluminum alloys will build aluminum oxide in an anodizing tank, so the answer to this question depends on the anodizing process and the desired result.  Copper containing 2000 series are generally the most difficult to anodize and 5000 or 6000 series are the easiest.
