Aluminum scrap?

\ Sure, cut away. It's plate that is covered with pure, or relatively pure, aluminum on each face. They use such metal for corrosive resistance, where greater strength is desired. That comes from the interior material, which is a specific alloy. I'm assuming you have (70)75 aluminum which is a zinc aluminum alloy. It's hard, but should cut fine. You'll notice it may take higher pressure to get it to cut, though.

It's 7075 with a layer of pure aluminum on either side for corrosion resistance (that's the Alclad part).

It'll cut fine with the same tools that you use on 6061.

Real nice stuff. Cuts well and cleanly.

Off top my head, has twice the tensile strenth of 6061----

Double check though, top of my head is way out there sometimes.

Well, not this time, anyway. Yep, it's almost double the tensile of 6061-T6. To my knowledge, it is the highest strength aluminum, rivaling cold rolled steel in strength. Michael has a good point when he prefers it to CDS for soft jaws. The only negative is that you can't weld new material to them to renew their useful life. .

But since I have a bunch of slugs from a material-supplied job in a box........When I make some, I do at least 2 sets. ;~)

Which should last you plenty long enough. Maybe you'd better send the rest of that stuff up before it rots. :-)
