Tungsten Rod (W-La 2%)

Description

The Tungsten Rod (W-La 2%) is a high-performance lanthanated tungsten alloy engineered for extreme-temperature and high-wear industrial environments, combining the refractory strength of tungsten with the enhanced electron emission and recrystallization resistance of 2% lanthanum oxide. It serves as a critical component in advanced arc welding (GTW – Gas Tungsten Welding), plasma cutting, thermal spraying, and high-temperature furnace systems. Strategically important for industries demanding operational uptime and precision, this rod delivers superior arc stability, longer electrode life, and lower consumption rates compared to conventional thoriated or pure tungsten alternatives—addressing both performance and regulatory compliance needs in global markets.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Tungsten (W) balance with 1.8–2.2% Lanthanum Oxide (La₂O₃) by weight

• Purity Level: ≥99.95% tungsten basis; low trace metallic impurities (<500 ppm total)

• Physical Form: Solid round rod, straightened

• Color Code: Light blue (industry standard for W-La 2%)

• Diameter Range: 0.5 mm – 10.0 mm (custom tolerances: ±0.05 mm standard; ±0.025 mm precision)

• Length: 100 mm, 150 mm, or 175 mm (custom lengths available)

• Density: 18.6 – 18.9 g/cm³

• Surface Finish: Ground, polished, or etched (as specified)

• Packaging Options:

  • Vacuum-sealed plastic tubes (10–50 rods per tube)

  • Plastic clamshells with anti-corrosion liner

  • Bulk cartons (500 rods per master carton)

• Shelf Life: Indefinite under dry, room-temperature storage (<70% RH)

3. Core Industrial Applications

Why this product performs better: Lanthanum oxide uniformly disperses within tungsten matrix, minimizing grain growth at high heat and enabling stable arc even at low amperage. Non-radioactive (unlike 2% thoriated tungsten), eliminating handling, disposal, and OSHA/EPA compliance costs.

4. Competitive Advantages
