COPALUM Crimp Method
Crimp with Confidence, Crimp with COPALUM

Here all the new copper wire has been COPALUM crimped to the existing aluminum wire found behind a switch plate. The crimps are color-sized depending on the wire sizes. The precision dies in the COPALUM tool squeeze the connector and wires into a particular shape using 10,000 pounds of force. The resulting crimp is now gas proof, without being subjected to oxygen no oxidation will occur

Next all the crimps are covered with a heat-shrink tube which provides very solid insulation

Finally, a heat gun is used to shrink the tubing over the completed crimps. The copper tails can now be connected to the new device completing the repair and in effect creating a copper only connection
Demonstration crimp
Now we have cut through the crimp to illustrate what happens to the aluminum and copper wires that have been crimped. The aluminum wire is now cold-welded to the copper wire creating a single wire that mitigates fire hazards effectively.

This is the primary reason that COPALUM™ crimping is considered a permanent repair.
Why does this work?
The COPALUM™ Crimp repair consists of attaching (pigtailing) a piece of copper wire to the existing aluminum wire branch circuit. These connections use a compression tool to fix the crimp. This process squeezes the conductor metal through small holes breaking down the oxidation layer and sealing the internal metal from any further oxygen contact
COPALUM™ Crimping is the only method considered a permanent repair by the US Consumer Product Safety Commission (CPSC), when applied to every aluminum electrical connection.
