Hard Anodized Aluminum

Rapid anodizing inc takes pride in their reputation as a leader in the anodizing industry.

Hard anodized aluminum.

To prepare aluminum for anodizing the surface is first thoroughly cleaned and rinsed and then placed into a bath of some electrolytic solution like sulfuric acid. An electrolyte is an electrically conductive solution with lots of positive and negative ions that it wants to swap. The process of anodizing the metal uses higher voltage and lower temperatures creating an even harder and more durable coating on the metal. However hard anodizing is commonly performed clear or with a black dyed finish though some prefer the aluminum dyed different colors for aesthetic purposes.

As a result this style of anodizing is also referred to as type iii or hard coat. Hard coat aluminum anodizing type iii to achieve greater corrosion protection for use in extreme environments or with moving mechanical parts the aluminum anodizing process can exceed depths 10 microns. Hard anodize coatings for aluminum are mostly used for their wear resistant characteristics and their resistance to corrosion hard anodizing works in two ways. It penetrates the parts surface and it builds up the layer on the parts surface and it builds up a layer on the parts surface approximately 001 to 006.

In applications where glass or porcelain would not have the strength or wear resistance to be a suitable substrate hard anodized aluminum is an excellent alternative.

Tie one end of the long aluminum wire to your anode. The area of the part that connects to the wire will not anodize. Anodized aluminum is aluminum that has been treated with a sulfuric acid bath while a low voltage current runs through the solution. While all anodized aluminum has been treated to halt oxidation hard anodized aluminum takes it a step further.

12 gauge aluminum wire works well for this use.

Aluminum hard anodizing also known as mil a 8625 type iii or engineered anodizing is similar to standard anodizing in that both are controlled electrochemical processes. Wrap it or connect it to the part in an inconspicuous area.

If your anodizing a key for example you may wrap the wire around the join between the blade and the bow. Depending on the process the solution may also contain oxalic acid.
