Does the assortment include square brass tubes?

I think there were 4 or 5 pieces of square tubing. I think slightly greater than 1/8 in outside, but all less than 1.25 inches long

are most of the tubes hollow?

Well, look at it this way; if it weren't hollow, I don't think it could be classified as a tube, do you? (are you serious?)

What percentage of this is aluminum?

in my assortment....as each one I have learned is quite different.,...I had about ten percent aluminum. but my real concern was the amount of very tiny...as in 20 or 18 gauge tubes...very very small virtually useless for me about another ten percent....!. Worth the price if you just want...a real ... assortment!

are there any pieces of copper tubing at least 1" long x 1" od in this assortment?

These are trimmings, so you never know what you'll get. The batch that I received were all smaller than 1" of, but several pieces were over 3" long. I received all brass and aluminum. For copper over 1/2", I go to the plumbing aisle of my local home store.
