Anodizing

ANODIZED ALUMINUM EXTRUSIONS

ALUMINUM ANODIZING

Profile Precision Extrusions provides the highest quality anodized aluminum tubing and extruded aluminum shapes in a variety of coating thicknesses and colors to meet your specific anodizing needs. We anodize extruded shapes and aluminum tubes in lengths from 1/4″ to 240″ and have no minimum order requirement.

What is Aluminum Anodizing?

Anodizing helps extend the life of aluminum by creating a chemically stable protective finish to make it resistant to corrosion and abrasion. It also enhances the cosmetic look of aluminum extrusions by using a variety of colors and mechanical finishes.

Benefits of Anodizing

  • Improved appearance
  • Abrasion resistant
  • RoHS compliant
  • Non-toxic
  • Chemically stable – will not decompose
  • Colorfast
  • Resistant to chipping and peeling
  • Cost-effective

The Process

Anodizing is an electro-chemical process that forms a durable, oxide coat on the surface of aluminum extrusions. Anodizing is accomplished by immersing aluminum tubes or extruded shapes in a tank containing an acid-based electrolyte and an electric current is passed through the solution. The aluminum extrusion serves as the anode, the tank and the cathode. The electrolyte releases oxygen ions at the surface of the profile, which immediately combines with the surface aluminum to form a hard aluminum oxide film.

Types of Coating We Offer

  • Sulfuric Anodizing Type II – Mil-A-8625 (Clear or colors)
    Sulfuric anodizing is the most common method for anodizing and is well-suited for applications where hardness, resistance and abrasion are required. This type of anodizing produces comparatively thick, transparent and absorptive oxide film, suitable for receiving both organic and inorganic dyes, and metal oxides for electrolytic color.

 

  • Hard Coat Anodizing Type III – Mil-A-8625 (Clear, gray or black)
    Hardcoat anodizing produces a very thick coat that is more resistant to abrasion and provides a smoother and harder surface.

 

  • Bright Dip
    Bright dip anodizing is a process where aluminum is chemically polished to bring out more brightness and bold colors in cosmetics applications. It will help protect the aluminum against scratching, fading and corrosion.

 

  • Chemical Film Coating (Clear & Gold)
    Chemical film anodizing is a process where a chromate conversion coat is used to protect the aluminum from corrosion, while still maintaining conductivity. It also can be used to improve adhesion for future paints or primers.

What Our Customers Are Saying

Jerry, the review of the initial 10 pieces is complete with no issues noted. Of particular note is both the effectiveness of the deburring and of the corner/edge break and the consistent appearance of the anodizing finish. Thanks again for the prompt turnaround on this request…

Profile Precision Extrusion is an awesome company to work with. They excel in all aspects and are an outstanding supplier.

Tony S

PPE has been providing us with precision extrusion for two years. PPE has consistently held tighter tolerances than other extrusion suppliers. They also have had “0” rejects and no late deliveries during the past two years. I would highly recommend PPE for your precision extrusions.

RIck M

The extrusions arrived today. You have exceeded my expectations. They look great and were very well packaged. Great job. More orders coming soon!

Tim A

It has been great working with you. It’s hard to find someone that is a dedicated to quality as you have been.

Tom B
