Finishes designed to last. Superior anodize coatings, for every load, every day.

Our Anodizing Processes

Sphere has established a reputation for our quality finishing standards. We pride ourselves on exceeding maximum finishing requirements. We provide our customers top of the line corrosion and wear resistance finishing on aluminum.


Sulfuric Acid Anodizing

This anodizing adheres to the military specification MIL-A-8625 Type II. We can do this in either Class 1 or 2 (non-dyed or dyed).


Etch Types

Sphere offers two etch types for your products. We can provide a smooth etch with a shiny finish, or an architectural etch for a matte finish.


Prototyping & Production Runs

Sphere provides early-stage Prototyping as well as Low, Medium and High production run capabilities.


Top Quality

We ensure we are always meeting the highest quality standards. ASTM Standards, including coating thickness, coating weight, density and die stain tests are performed. Sample analysis is done on a bi-weekly basis by an external lab. Tank concentrations are checked, controlled, and documented daily. C of C’s available upon request.


Chemical Film

A chromate conversion coating that enhances corrosion protection while still maintaining conductivity. This trivalent (clear chromate) finish is RoHS compliant.

Key Benefits

Protection and Durability

The number one benefit of anodizing your aluminum is protection. Once the aluminum has been anodized, it becomes very resistant to corrosion due to the thicker layer of oxide. Anodized products have a very long life-span.


Standard aluminum does not typically support dyeing, so products are restricted to the natural chrome colour. Anodized aluminum offers a wide range of colour and gloss options for aesthetic appeal, while still maintaining its metallic appearance.

Environmentally Friendly

Anodizing uses simple inorganic chemicals that have a minimal impact on the environment.

Cost Effective

Compared with powdercoating or painting, anodizing provides additional benefits while remaining price competitive.
