Can most powdercoaters' ovens hit 800 to 900 degrees F?

Hi, everyone.

I have some sheet amluminum that I'd like to anneal.

I've been trying the old world technique of hitting it with a light coat of acetylene soot, and then burning off the soot with a neutral flame. So far, I can do a small section fine, but I can't do a 2' by 5' piece. I get a spot too hot which completely defeats the purpose.

So I thought that if I could get a powedercoater to bake these sheets for however long it takes to get it up to 800 degrees, I'd be all set. Do powdercoating ovens go that high? If so, does anyone know a powdercoater around Pittsburgh that would be game for a few quick bucks?

Thanks in advance,

Matt

I think they are closer to 500 Degrees.........OLDBEET

I'm guessing you've already read this:http://www.metalshapers.org/tips/covell/annealing.htm
Powder Coating is usually in the 400-500 F range,so I'd be suprised if the oven would go that high.
But the guys that do heat treating will have a tempering oven that will go to 800 no problem.
Just look in the phone book under "heat treating".

If a powder coat oven gets hot enough to anneal, what will that do to a Mag Wheel when it gets coated?
Or is that not something to worry about?

if you should happen to know a powder coater that does header coatings(the shiny shit,jet-hot style),that stuff is baked on at 850-900 degrees,before it is polished.
they may anneal it for ya'
hope that helps.

Thanks, guys.

I never thought of either the heat treaters or the ceramic header coaters.

Unkl, that's exactly what I was trying to do. But I wasted a couple of carefully cut pieces because I'd crystalized the aluminum. Actually, I could do a better job with a proper steel table than I could with my current Mickey Mouse setup on the concrete floor...
