Is it still called angle iron if it is made of aluminum?

Scrap Attack is part of this nutritious breakfast.

I got tired of carrying stuff from the kitchen like this, so I built a tray from scrap aluminum and wood.Aluminum angle pieces courtesy of the scrap bin at school:Thin wood piece from shelf drawer, I cut it with aviation snips to this size. There is absolutely nothing wrong with cutting wood with aviation snips.... well until it cracks. Cutting the aluminum to length with hacksaw. I clamped the vise to the table to make it easier.Deburring the sharp edges with a file.Drilling the holes, I clamped it all so I could drill through all 3 pieces at once. Center drilled first, then through with a 1/4" bit, and deburred with a countersink.Fastening it all together with stainless steel #10-32 screws and nuts.Here is a view of the bottom. I assembled it so the tray will sit on the round heads of the screws.All done!
