CuZr. C15000, RWMA Class 1. Superior electrical conductivity, resistance to sticking and annealing make this copper alloy material one of the most cost effective materials for welding light-to-medium gauge coated and uncoated steels.    

Z-Trode® is the ideal cap electrode for resistance welding of light-to-medium gauge coated and uncoated steels and aluminum alloys.  

Sticking is inevitable when you weld galvanized steel with conventional electrodes. The chrome in conventional electrodes encourages the alloying of the zinc and copper to create a brass alloy surface that stops the welding dead. But Z-Trode is an alloy of zirconium and oxygen-free copper. The zirconium discourages the alloying effect on the electrode face and prevents sticking.
