CuCrZr. C18150, RWMA Class 2. The lower percentage of chrome in comparison to the standard Class 2 CuCr material and the addition of Zr to this Copper alloy discourages the alloying affect of zinc and copper to form brass on the electrode face and helps to prevent sticking.

Luvata's A-Trode® is the universal cap electrode for reliable resistance welding of light-to-medium gauge coated and uncoated steels.

Produced by Luvata's proprietary billet casting process, the A-Trode's freedom from oxygen allows us to alloy the copper with the optimum levels of chrome and zirconium to deliver consistent welding results.

The A-Trode is available in all industry sizes, geometries and tapers or cold headed or machined to deliver your custom-made shape.
