How To Anodize Aluminum Black

Use 6061 or 6063 aluminum cathode at a ratio of 1 to 3 times more part area than cathode area.

How to anodize aluminum black. Place a lead cathode in the bath. Anodizing again might look complex, however, the steps are straightforward. An ongoing discussion from 2000 through 2019.

After hard anodize, the part may be machined, ground, honed, lapped or stripped to remove areas of the coating. Anodize at 15 volts for 30 to 45 min in a 15% by weight solution of sulfuric acid at a constant 72 °f. Unlike paint, which can flake off if not applied properly, anodized finishes are actually formed from the.

We have any size you need up to 4'x10' sheets. The black finish is matte, while the gold and silver finishes are brushed to mask fingerprints. Make a 2% (dilute) solution of sodium hydroxide (drain cleaner, naoh) if you desire an etched surface prior to anodizing.

This should have a surface area of at least twice that of the aluminium part. Displaces water and seals out atmospheric humidity. A power source with connections;

To cut, use a circular saw or jig saw fitted with a saw blade designed to cut sheet metal (fine tooth blade). This is real commercial grade aluminum aa5005. Matte anodize can be achieved by matte etching the aluminum prior to anodize.

Dye (only needed if you want to make it a different color) aluminum or titanium wire; A clean water rinse removes residues: First, cleaning of the aluminum part occurs before undergoing anodization.
