I will say that the material edges are a bit rough. The ring lord is very inexpensive, you can see why when you get your order. I’d order from them again but only for things where you don’t need top quality.
I don’t know how strong the resistance is, you might want to look up its dielectric constant if you have a concern there. Also, it’s prone to scratching a bit, I don’t know how deep the scratch would need to be to expose the conductive substrate.
The cut edges of the card would be a problem, they are bare metal. And it’s not clear if the engraved areas are conductive, I didn’t test that, and my test pieces are up in the house, not down in lasertown so I can’t check it.
Get it burning and toss in water, but have lots of protection. It will yank the oxygen right out of the hydrogen. As the British discovered in the Falklands dust up. That great idea they had of making military battleships in aluminum turned out to not be such a good idea after all.
I think those turned out very nice. The things I have gotten from the ring lord are pretty comparable to Chewbarka’s stuff. Yes the edges are a bit sharp, but for the price I think it is a pretty good deal.
Anodizing actually forms a non-conductive layer of aluminum oxide, its like ceramic. It is done in a 15% sulfuric acid and distilled water bath with low current DC electricity. When finished, the ceramic will accept a dye for color.
I bead blasted a used aluminum shotgun upper receiver, cleaned it, got a battery refill kit from AutoZone, diluted the acid to the proper mix, added a big aluminum plate to the bottom of the bucket. (Cathode must be larger than the anode / the piece you are anodizing.) I ran 12v DC from an Astron power supply to the shotgun receiver for several hours. it came out beautifully. I made a bath of RIT clothing dye, heated it on the stove to 100 degrees. dipped the part in there for 15 minutes, then boiled in clean water for 30 mins, and it is perfect. I did the rest of the shotgun and parkerized the ferris metals. I added a tactical stock and turned a used turkey shotgun into a very practical home defense shotgun.
