Just got back from the scrapyard, picked up 68lbs. of aluminum and some angle iron for $50. At least I was told it was aluminum. Looked much too heavy and on attempting to cut it up, it sure as hell ain't... can't cut jack with a hacksaw blade, but it's nonmagnetic. It has edges showing a nice gray break (like aluminum or hardened steel, although hardened steel is usually much finer than this).
The shape is some sort of grate, 1/4" bars spaced about 5" with rings (cored holes) at each intersection, and a uniform height of about 1 1/4". It's almost nonmagnetic.
What the heck is it!?
