NP547 - 3/32" Zirconiated White Tungsten Electrodes for Aluminum TIG Welding

High-Performance Zirconiated Tungsten Electrodes for AC Welding

Optimize your aluminum and magnesium welding applications with our premium Zirconiated Tungsten Electrodes. Identified by the industry-standard white color code, these electrodes are specifically engineered for Alternating Current (AC) TIG welding, offering a superior balance between the arc stability of pure tungsten and the current-carrying capacity of alloyed alternatives. The 3/32-inch diameter provides excellent versatility for medium-to-heavy gauge materials, making it a staple in fabrication shops, aerospace maintenance, and automotive repair facilities.

Zirconiated tungsten (AWS classification EWZr-1) contains a small amount of zirconium oxide, which significantly enhances the electrode's performance characteristics compared to pure tungsten. It excels at retaining a balled end during welding, which is essential for maintaining a stable arc and achieving the necessary cleaning action on aluminum surfaces. Furthermore, these electrodes demonstrate exceptional resistance to contamination, ensuring that the weld pool remains pure and free from tungsten inclusions. This makes them an ideal choice for radiographic-quality welds where structural integrity is paramount.

Unlike thoriated electrodes, zirconiated tungsten minimizes the risk of spitting, even at higher amperage settings. While primarily designed for AC applications, they offer reliable arc starting and consistent performance. These 7-inch electrodes are ground to precision tolerances to ensure consistent conductivity and fitment in standard TIG torches. Whether you are welding thin aluminum sheet or thicker structural components, the T332X7ZIR electrode delivers the control and quality required for professional results.

Key Industrial Benefits:

• Enhanced Current Capacity: Handles higher amperage loads than pure tungsten without breaking down.
• Contamination Resistance: Resists spitting and tungsten inclusion, vital for X-ray quality welds.
• Stable Arc Profile: Maintains a perfect balled tip for consistent AC sine wave distribution.
• Material Specificity: Optimized specifically for aluminum and magnesium alloys.
