Cu / Al connections ... small wires

[lakee911]

What is the proper code compliant way to join old small gauge aluminum (#12, #10, etc) building wiring to new copper?

Can this aluminum wiring still be purchased (say for repairs)?

Thx

With listed products, identified for the purpose, per the product markings, labels, and / or installation instructions.

You can buy new generation aluminum wire.

Good deal, buy 'em. Best price for small quantities I've found here is $23.97 for ten.
