Short answer: Copper conducts about 100 percent IACS with excellent joint reliability and low creep for busbars, motors and earthing, while aluminum conducts about 61 percent IACS but weighs a third and costs far less, so aluminum wins long spans and weight-sensitive runs where joints are done with proper anti-oxidant and torque, and copper wins where reliability and compact size matter most.
At a Glance
What Conductors Need
Conductivity, weight and joint life lead the choice, with the basis in our Metal Strength Comparison and expansion notes in our Thermal Expansion Guide; electronics context is in our Electronics Guide.
Copper and Aluminum Stock
Copper leads reliability and aluminum leads weight and cost, with the copper basis in our Copper Supplier and aluminum in our Aluminium Supplier; busbar context is in our Power Transmission Guide.
Joints and Care
Aluminum joints need anti-oxidant compound and correct torque to avoid creep and heating, with joining notes in our Welding Joining Guide and data-center context in our Data Center Guide und EV Charging Guide.
Quality and Sourcing
Conductor metal is checked by inspection, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
