1. Exceptional High-Temperature Performance:
High Melting Point and Stability: Preserving tungsten's high melting point characteristics while ensuring structural stability at elevated temperatures.
Higher Recrystallization Temperature: Recrystallization temperature exceeds that of pure tungsten by approximately 150 °C, allowing for better performance retention at high temperatures.
Outstanding High-Temperature Creep Resistance: Maintains shape and resists deformation under high-temperature conditions.
2. Superior Mechanical Properties and Machinability:
Increased Strength and Hardness: Studies indicate that properly processed tungsten-lanthanum alloy rods exhibit higher hardness values compared to pure tungsten.
Improved Ductility: The ductility at room temperature and elevated temperatures surpasses that of pure tungsten, providing superior machinability. The surface finish after turning is also notably smoother.
3.Exceptional Electrical Performance as Electrodes:
Tungsten-lanthanum electrodes demonstrate lower electron work function, leading to superior arc initiation and stability while contributing to lower electrode burn-off rates.
4. Environmentally Friendly Alternative:
Unlike thoriated tungsten, tungsten-lanthanum alloys contain no radioactive materials, making them a safer and eco-friendlier option for various applications, especially in settings requiring stringent safety standards.
