Looking to do my first annodize and have a question

[NeoWeird]

If I want to do a plain jane annodize with no dye on some 7075 aluminum, it will come out a very flat black, correct? What steps/procedures can I cut out of the whole annodize step if I don't want to dye it and just want that flat black annodizing?

With no dye, when you anodize you should have a clear, or very close to clear layer of anodize, what you will need to do to seal this is boil in hot water, hold it in the steam for a bit before you dunk it in. Anodizing produces clear layers, dye can be added to change the color, hope tis helps. Read the anodizing instructions, lots of good info.

Flat black is achieved with material finish and black dye. The matte finish I get is from blasting with glass bead. There are not any steps you can cut out of the process. The only step you can delete in anodizing is the dye step if you don't want any color, but the part will be close to the original color or have a slight yellowish tint if you have a real thick coating.

If you want a 'flat' black, you should lightly sandblast or buff with a scrubber buffing wheel. Then you will need to dye the part. The 'flatness' will depend entirely on the prep finish.

I may have read it wrong, what color do you want the finish product to be ? If you want a black, you need to use black dye, if you want a silver/natural aluminum finish then no dye is needed.
