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 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 protects and extends the life of aluminum extrusions by creating a chemically stable aluminum oxide coating that is resistant to corrosion and abrasion. It can also enhance the cosmetic look of aluminum extrusions and tubing by applying a variety of organic colors during the anodizing process.
Benefits
- 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.
- Chemical Film Coating
Chemical film is a process where a chromate conversion coating is applied to protect the aluminum from corrosion, while still maintaining conductivity. It also can be used to improve adhesion for future paints or primers. RoHS compliant versions are available.
FABRICATION & MACHINING
Profile Precision Extrusions offers complete turnkey fabrication and machining services.
Our fabrication services not only save you time by simplifying your manufacturing value chain, they also save you money
For development projects we are happy to manufacture a small number of prototypes.
The fabrication and machining services we offer include:
CNC Machining
Computer numerical control (CNC) machining is a process utilizing computer automation of machine tools that are operation by precisely programmed commands in a software program as opposed to controlled manually.
Cut-to-Length
.250” – 240.00”, Tolerance to +/-.005”
Tumble Deburr
This is a finishing method that is used to remove sharp edges of cut parts. It also improves cosmetics and functionality of each part.
Centerless Grinding
This is very precise process removes metal by grinding the surface of a tube or round bar.
Laser Part Marking
This process creates permanent, non-contact, and high visibility laser marks for engraving.
