T1167GZ - 1/16" Zirconiated Tungsten Electrodes (White) - 7" Length for Aluminum TIG Welding

Professional Grade Zirconiated Tungsten for AC Applications

The T116X7ZIR Zirconiated Tungsten Electrodes are engineered specifically for high-precision TIG welding of aluminum and magnesium alloys. Distinguished by their white color code, these electrodes contain approximately 0.8% Zirconium Oxide (ZrO2), a composition that offers significant performance advantages over pure tungsten (green) when utilized in Alternating Current (AC) welding processes. This specific formulation allows the electrode to retain a balled end during welding, which is essential for maintaining a stable arc and achieving deep, clean penetration in non-ferrous metals.

One of the primary technical benefits of Zirconiated tungsten is its high resistance to contamination. Unlike pure tungsten, which can degrade and spit under high thermal stress, Zirconium Oxide reinforces the tungsten matrix, allowing it to handle higher amperage loads without compromising the integrity of the weld pool. This makes the T116X7ZIR an excellent choice for radiographic-quality applications where tungsten inclusions must be strictly avoided. The electrode provides an extremely stable arc in both balanced and unbalanced wave AC TIG welding, ensuring consistent bead profile and reduced post-weld cleanup.

These electrodes measure 1/16" (1.6mm) in diameter and come in the industry-standard 7" length, making them compatible with standard TIG torches and consumables. While they share some characteristics with Lanthanated electrodes, Zirconiated tungsten is uniquely optimized for AC sine wave power sources and older transformer-rectifier machines, though it performs exceptionally well on modern inverters as well. It is important to note that while these electrodes excel in AC applications, they are not recommended for DC welding. For industrial fabricators working extensively with aluminum piping, automotive components, or aerospace structures, the T116X7ZIR offers the reliability and arc control necessary for professional results.
