You just have to not mix and match. If you mix them the two need special bonding at every single connector or they can cause arching and fires. | ||

If by “special” you mean ordinary low-cost lugs, then sure. Check it out: https://lugsdirect.com/WhyAluminumOverCopperFAQ.htm And you can browse that site for lugs, and they’re mostly rated for aluminum and copper. Copper-only lugs are actually rather unusual. Sure, you can’t stick copper and aluminum wires into a wire nut, and finding terminations for smaller-gauge aluminum wire can be hard. But for larger wire, it’s really no problem. | ||

Most wiring device terminations and lugs are Al/Cu rated. You’re supposed to use specific fittings for splicing together aluminum and copper wire (specific WAGO lever nuts are UL listed for this purpose along with some others), I assume that’s what you meant. | ||
