Anodized for industrial products
We offer anodizing type II and III, which are ideal surface
finishes for aluminum parts.
Anodizing strengthens aluminum parts and is available in several
colors, depending on the type.
All types of anodizing will increase the lead time and cost per
part.
| Surface preparation | Colors | Glossiness | Cosmetic availability | Thickness | Visual appearance |
|---|
| As machined (Ra 3.2μm / Ra 126μin) | Clear, Black, Red, Blue, Orange, Gold | Glossy (Above 20 GU) | No | 50μm to 150μm | Parts are anodized directly after machining. Machining marks will
be visible. |
| Bead blasted | Clear, Black, Red, Blue, Orange, Gold | Matte (Below 10 GU) | Cosmetic on request | for clear: 8 to 12μm(0.0003” to 0.0004”) black and color: 12 to
16μm(0.0004” to 0.0006”) | Grainy texture, matte finish |
| Bead blasted | Clear, Black, Red, Blue, Orange, Gold | Glossy (Above 20 GU) | Cosmetic on request | for clear: 8 to 12μm(0.0003” to 0.0004”) black and color: 12 to
16μm(0.0004” to 0.0006”) | Grainy texture, glossy finish |
| Brushing(Ra 1.2μm / Ra 47μin) | Clear, Black, Red, Blue, Orange, Gold | Glossy (Above 20 GU) | Cosmetic on request | for clear: 8 to 12μm(0.0003” to 0.0004”) black and color: 12 to
16μm(0.0004” to 0.0006”) | Parts are manually brushed to reduce marks, then anodized. Brushing
lines will be visible |
| Surface preparation | Colors | Cosmetic availability | Thickness | Visual appearance |
|---|
| As machined (Ra 3.2μm / Ra 126μin) | Black, Natural (thicker layers will appear darker) | No | 35 to 50μm(0.0013” to 0.0019”) | Parts are anodized directly after machining. Machining marks will
be visible. |
What is Anodize for CNC Machined Metal Parts ?
Anodizing is a common surface treatment method for CNC machining
metal parts, especially aluminum.
This is an electrochemical process that forms a controlled oxide
layer on metal surfaces. Anodizing has several advantages,
including enhanced corrosion resistance, improved wear resistance,
increased surface hardness, and the ability to add color or dye to
the metal.
Anodizing can produce a variety of surface finishes, including
natural silver (clear anodizing), and various colored finishes
achieved by dyeing the anodized layer. Color can be absorbed into
the porous oxide layer, providing an aesthetic option for CNC
machined parts.
The anodizing process adds a layer rather than a coating to the
surface of the metal, meaning the treatment doesn’t significantly
alter the dimensions of the part. This makes anodizing a popular
choice for CNC machined parts that need to be held to tight
tolerances.
