Thread: Any guess as to what type of metal this is?

    So a quick update, Disney went above and beyond, searched through their archives and found both the source photo and tile photo. We're talking about pics from 14 years ago, from a program that ended in 2007. I can't wait to give it a shot and I'll post the pics once I'm done. Can't wait!

    Anyone have any suggestions on cutting. 025" (.635mm) thick aluminum? I don't think hand shears will work.

    You can cut .040" aluminum with engraver's type metal shears. Here's a good one from Johnson Plastics

    The product description says .025". It's LaserBlak sheets. I bought an 14 gauge electric metal shear and it was garbage, but this is a one off memorial gift so it's not a huge deal I guess. If I ever decide to do this for my business, I'm going to buy a more precise piece of equipment.

    You could have used a utility knife and straight edge to make the "cut". Then just sand the edges down a bit.

    Try aluminium. Spray paint it with spray paint all around to the back and side. And then mark it with laser. Low power. Just enough to remove paint chose one with your needed durability rating.

    After getting the right image, but not in reverse, you go get some NaOH, soda ash, i think... u can get from supermarkets. Those that

    Mix with water. Need not be particular with concentration. Just dump till it is warm and not too hot. Just normal room temp water to warm and immerse. U will see hydrogen. It is reacting with the alum. Open room is good for explosion prevention. And please dont smoke while doing this.

    The NaOH will not affect paint. But will eat away aluminium, giving a very beautifully clean satin finish. Keep agitating to prevent pitting and dimpling and to speed up process.

    3 minutes or until you get it deep enough. Quench with lotsa cool water and you are done.

    Marco, and I suppose other suppliers, sell an outdoor gloss black laserable aluminum-- PN 8114-6 on page 24 in the 2016 Marco catalog--

    I've been using this stuff for a couple of years, it's perfect for this- it's .040" thick, the gloss black surface is close to semi-gloss in my opinion- lasers easily and the resuting silver isn't all that glossy. You would simply need to run the engraving in negative leave the black remaining while the laser creates the 'white'.

    Thanks everyone. I ended up using the LaserBlak and it came out great. The cut was pretty much garbage, but since I ended up framing and matting it, you don't see the edges anyway. I'll try and post a few pics soon. I'll be giving it to him this weekend.
