Corrosion resistance

Increases resistance to corrosion without adding a thick layer to your part

Pair with 7 post-processing services

Anodizing pairs well with a variety of our other sheet metal or CNC machining services

Tight-tolerance friendly

Adds only 0.0002″–0.0009″ per side, so anodizing won't affect fit on parts with mating surfaces or threaded features.

“One of the biggest surprises was their anodizing quality—not only was it significantly more affordable than I expected, but the finish was also top-tier.”

Chase Doney

Available materials for Anodizing

Many non-ferrous metals can be anodized, but aluminum is the best candidate and creates the most successful finish. At this time, we offer three different aluminum alloys for sulfuric anodizing:

Design guidelines for anodized parts

Following a few basic design guidelines will help ensure your parts anodize properly and pass SendCutSend review.

Sizing & hole requirements

Sizing limits apply to flat parts  before bending for sheet metal

Sheet Metal

Min part size (flat)1″ x 3″ (≥ 3 in² surface area)
Max part size (flat)23″ x 23″
Required hanging hole≥ .063″ (1.60 mm)
Min hole / cutout size ≥ .040″ (1.02 mm)

CNC Machined Billet

Min part size (flat) 1″ x 3″ x 1″
Max part size (flat) 7″ x 7″ x 12″
Required rack feature One ≥ .125″ through hole (best), or a threaded blind hole ≥ 4-40 / 3mm with ≥ 1.5× diameter depth
  • If your billet design can’t accommodate a hole, we can pinch opposing surfaces during racking.
  • Expect small marks of discoloration at pinch points. You can specify preferred surfaces in your order note during configuration.
  • If your material’s min hole size is larger than .063″, the hanging hole must match that larger size. Verify in the Material Catalog.
  • Deburring is preselected on all anodized sheet metal parts. Media blasting is strongly recommended for billet.

What to expect with anodized parts

  • Some surface imperfections may be visible through the anodizing
  • Color finishes may vary batch to batch, and significantly between alloys
  • 7075 T6 Aluminum will appear duller with more contrast between face and cut edge
  • Bend lines will be visible (die protection isn’t available)
  • Anodizing is non-conductive
  • Scratches will expose raw aluminum beneath
  • Type II anodizing adds ~0.0002″–0.0009″ per side to part dimensions
    Parts requiring welding should not be anodized
  • Without deburring (sheet) or media blasting (billet), all imperfections are enhanced

Additional anodizing resources

If you’re designing parts for anodizing, these resources may help:

Pre-flight checklist: Sheet Metal

  • File is in a format that we accept (2D: .dxf, .dwg, .ai, .eps; 3D: .step or .stp)
  • 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
  • 2D files: all objects on the same layer, text converted to outlines, no open contours, all shapes united or merged, floating interiors bridged or stencilized
  • 3D files: single solid sheet metal body, uniform thickness with a face at every edge, modeled at stock thickness with matching bend specs
  • All stray points, duplicate lines, empty objects and text areas have been removed

Pre-flight checklist: CNC Machined Billet

  • File is in a format that we accept for CNC machining (.step or .stp)
  • Only one part is present in your design file (no assemblies)
  • File is built at a 1:1 scale in either inch or mm units
  • File does not include any extra faces or entities
  • No holes or features are smaller than .125” (3.175mm)
  • Internal features will have a minimum radius of .0625” (1.587mm)
  • All internal features are accessible (e.g., not fully enclosed)
  • No part marking, etching, or engraving included in the design
