Anodizing

Protocase is pleased to offer Type II and Type III anodizing.

Anodizing involves an acid bath and electricity which, when used together, is a controlled oxidization that enhances the naturally occurring oxide layer on aluminum. It is this controlled oxidization that makes the oxide surface thicker and therefore, stronger.

The aluminum is secured to racks and then lowered into an acid bath. An electric current is then passed through the racking and into the aluminum part. The anodized aluminum can be left in its natural color, or dyed from many color choices, using organic dyes.

Anodizing: Type II Vs Type III

Also known as common or standard anodizing, Type II is sulfuric acid anodizing (as opposed to Type I anodizing, which is chromic acid anodizing).

Type II anodizing includes two different classes:

  • Class I signifies an un-dyed finish, also called clear or natural
  • Class II signifies a dyed finish and the color is named ( i.e.: Type II Class II Red )

Type III anodizing is also sulfuric acid anodizing. The key difference between Type II and Type III is that for Type III anodizing, the sulfuric acid solution's temperature is lowered and run at a higher voltage.

The end result is a denser, wear-resistant oxide layer that creates a harder and smoother finish than Type II anodizing. Type III anodizing is ideal for parts that rub together.

Why Anodize?

There are many advantages to choosing an anodized finish for your enclosure, part or component:

Durability: Because anodizing creates an extremely hard surface, the finished product will have a very long lifespan and require very little maintenance.

Aesthetics: Color (Class II) anodized aluminum maintains its vibrancy in spite of prolonged exposure to UV rays, and will not chip or peel.

Resistance: Anodized aluminum is resistant to corrosion, heat and electricity.

Environmental: Anodizing produces a non-toxic finish, with no harmful by-products.

Lead Times:

Anodizing is completed off-site via a third party supplier. This means there is additional lead time.
