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.

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.

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 1,221F(the melting point
  of aluminium)
•  
• Anodizing uses simple water based chemicals that
  can be treated easily and that release no harmful
  by products

• 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

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.

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.
