WLa Alloy

WLa Alloy – High-Performance Lanthanated Tungsten Alloy | Focuswmo

Focuswmo supplies premium-grade WLa alloy (Lanthanated Tungsten Alloy) designed for high-temperature, high-load, and long-life industrial applications. With exceptional thermal stability, enhanced electron emission, and superior creep resistance, WLa alloy is widely used in welding, lighting, aerospace, and high-temperature furnace components.

What Is WLa Alloy?

WLa alloy is a tungsten material doped with 1–2% lanthanum oxide (La₂O₃), offering improved ductility, ease of machining, and resistance to recrystallization compared to pure tungsten. It delivers stable performance under extreme heat and mechanical stress.

Key Features of WLa Alloy from Focuswmo

- High Recrystallization Temperature: Ensures exceptional stability during prolonged high-temperature operation.

- Excellent Electron Emission: Ideal for electrodes, filaments, and vacuum components requiring consistent emission performance.

- Enhanced Ductility & Workability: Lanthanum oxide refines the grain structure, making forming and machining easier.

- Long Service Life: Reduced evaporation rate and improved creep resistance allow reliable performance under extreme load.

- Corrosion & Oxidation Resistance: Suitable for challenging environments such as plasma welding and high-vacuum systems.
