You cannot use them with Al. The connection will disintegrate over time.
I have pictures somewhere of mismatching rail bonding connectors that
were gone in a year. Chris

Our electrical supplier seamlessly transitioned from crimp on butt end
connectors, that were listed for CU and AL, to unmarked ones that were
approved for copper only.
I became concerned since there was no marking. Calling two electrical
suppliers, the guys at the counter had to look up the device to learn
that they were listed for copper only. Talking to one of the counter
guys, he agreed that electricians were probably using these for aluminum.
Since the barrels will be insulated, it is not likely that inspectors
will see them. The connectors are made of coated copper. I wonder how
much of a problem this will be.
