"Blueing" aluminium?

[jg007]

Got a little hammer happy on some lower receiver roll pins, any way to blue / blacken the aluminium short of cerekote?

Bluing reacts with the iron in steel, aluminum is non ferrous. Birchwood Casey sells Aluminum Black but I've never had anything but crappy results. It leaves a flat black residue like carbon from a match, it wipes right off. Careful masking and some krylon flat black is usually what I use for small touch ups.

anodized finish is usually used on Al

The frame is anodized aluminum.

It's a loosing battle keeping a firearm in like-new condition. Anyway, IMHO, a work gun should like a work gun, kinda like a work truck

That's what I was trying to remember. Birchwood Casey's! Thx. Too bad you had crappy results. Maybe I'll just spray it, or beat it up

Birchwood Casey has a "pen" called Super Black (flat). It's more like a flat paint. I use it on Aluminum and my front sight on my S&W 639, so far so good.

The Aluminum black needs a few coats. The make up of the aluminum will decide how the black turns out.

I've use the Birchwood Casey Aluma Black and it works great.

I did not think Amazon would ship it to Canada when I looked last year, however that may have changed. I did find this supplier in Canada of Aluminum blacking

Wonder if it's the same kind of solution like the Birchwood stuff.
