I recently was scrapping a flat screen tv with the screen broken bad enough that popped off. The metal shell on the inside had strips metal that had wires attached to them. What are these strips? My guess is aluminum but I want to be sure what bin I put them in.

Tiny thin strips sticky on one side? Yes, normally aluminium

Those will be the ones. Thanks!!!! Though I was hoping they were some special circuit board that was worth a million dollars each.

Nope. You’ll occasionally find tin alloy in very old flat screens. Especially televisions. They’re extremely hard to bend.
The most common alloy I’ve seen was tin nickel steel. And it gets a very low end tin alloy rate if you have enough and the yard is big enough. Probably on the 50-75 cent range right now. For a smaller yard you’ll probably get tin can rate.

Post a picture?

I can only think of the led strip in what he is explaining or the Aluminium bar that the leds/bulbs are fixed to.

Op is talking about the strips that hold things together. About half an inch long. Quarter inch or less wide.
The exact same strips of metal are found in laptops holding wires down. In feature phones holding the boards together.
In most non-top-tier cell phones holding the battery to the case and boards.
Amazon uses it in the kindle and fire lines.

A more extreme example is if you every opened up an early plasma display or TV they all used 9.5” and 4” long strips holding the boards to the plastic back panel of the display.

The first generation Sega Saturn is full of these little guys across the battery. Over the region jumper pins. For some unknown reason two were added to the primary processor heatsink. As if the (legitimate super) glue wasn’t enough. Two around every port connector.

It’s basically super duty foil (commercial oven liner) with a glue on one side.

Yep. The vast majority of such bracing tape is aluminium.
If you come across tape you have trouble or can’t bend with your own fingers you found a tin alloy.
