Review on King Innovation 95015 AlumiConn Connector by Seth Singh

Ideal for joining copper and aluminum wires and terminals. If feeding must continue, use a three-port connector. I've used both and they work well and give security when it comes to wiring in a house with aluminum wiring. Of course, replacing the wire with copper is the best solution, but in most cases it's easier said than done. These connectors have proven to be secure when properly installed. This means that you use a torque screwdriver when installing. (Bought from Home Depot for a pretty cheap price)
