Pricing/Order Information
Quantity reductions begin when you order more than one of an identical part, with an anodizing minimum charge of $9 added to your order.
While we strive to mill and process your components as quickly as possible, anodizing will extend the processing time for your order by an additional 7–10 working days.
We advise separating any items that need anodizing into their own separate order for the fastest turnaround times. This enables us to process the anodised parts separately and dispatch your non-anodized parts as soon as they're ready.
Materials Available
Although a variety of non-ferrous metals can be anodized, aluminum is the ideal choice and yields the nicest finish. For sulfuric anodizing, we now provide three distinct aluminum alloys:
​
-
5052 Aluminum: .063-.500″ (1.6 – 12.7mm)
-
6061 Aluminum: .063-.500″ (1.6 – 12.7mm)
-
7075 Aluminum: .125-.250″ (3.18 – 6.35mm)

Geometry Requirements
Parts need to meet certain requirements in order to be anodized successfully.
To meet handling and deburring requirements, all anodized pieces must be at least 1′′ x 3′′ in size. The part's total square size should be no less than 3, and the shortest dimension must be less than 1".
​
A maximum of 23" x 23" can be used for anodized pieces. The maximum size of the item can be limited by anodizing, but your parts must also adhere to the deburring geometry specifications. On all anodized parts, deburring will be a pre-selected option.
All anodized pieces must have a hole for processing, per our specifications. The hole must be at least.063" (1.60mm) in diameter; however, if the material and thickness you have chosen have a minimum hole size that is larger, the provided hole should line up with that size.
File Setup
Check out our instructions for designing and setting up your files in Illustrator, Inkscape, and Fusion 360 if you discover after reading these suggestions that you need to make any adjustments to your part design.
What To Expect
-
Some imperfections may be visible through the anodizing
-
Color finishes may vary from batch to batch
-
Different alloys will have significantly different color finishes
-
Anodized 7075 aluminum parts will have duller coloring and a more pronounced difference in appearance between the face and cut edge due to the high zinc content of the material
-
If deburring is omitted, all imperfections will be visible and enhanced in severity
-
We strongly recommend utilizing our free deburring service alongside anodizing
-
Parts requiring welding should not be anodized
-
Anodizing is non-conductive
-
The anodizing can scratch and raw material will be visible below
-
Bend lines will be visible through the anodizing (die protection is not available)
-
Type II anodizing will add ~0.0002”-0.0009” per side to the surface of your parts
-
Type III hard anodizing will add ~0.0005”-0.001” per side to the surface of your parts
Pre-flight Checklist
Before you upload your design files, be sure to go through our pre-flight checklist:
File is a two-dimensional vector format file.
All holes and cutouts are at least 50% material thickness for laser cut parts
All holes and cutouts are no less than 0.070” for most waterjet cut parts
All holes and cutouts are no less than 0.125” for all CNC routed parts
File is built at a 1:1 scale, preferably in inch or mm units
All objects are on the same layer
All stray points, duplicate lines, empty objects and text areas have been removed
No shapes have open contours
All shapes have been united, combined or merged
All text has been converted to outlines or paths
Cut-out text (reversed text) has bridges or has been stencilized
