EWZr-1 (WZR3) — Zirconiated Tungsten Electrode (Brown) — Overview

EWZr-1 Zirconiated tungsten electrodes (WZR3 grade) are designed for AC TIG (GTAW) welding of aluminum and magnesium in high-purity applications. As a non-radioactive electrode, WZR3 forms a balled end with ease under AC current and provides superior current capacity with minimal tungsten contamination — the preferred choice where weld purity is critical. Conforms to AWS A5.12. Pack of 10 × 7-inch electrodes. Ships across Canada from North York, Ontario.

Key Features

  • Classification: EWZr-1 (WZR3 grade) — non-radioactive
  • Forms a balled end easily under AC current — optimal for AC aluminum and magnesium welding
  • Superior current capacity at high amperages
  • Minimizes tungsten contamination — preferred for high-purity welding applications
  • Brown colour band for quick identification per AWS A5.12
  • Pack of 10 × 7-inch electrodes

Applications

  • Current type: AC (Alternating Current)
  • Base materials: aluminum alloys, magnesium alloys
  • Ideal for: high-purity applications where tungsten contamination must be minimized
  • Process: TIG (GTAW)
