WL 10 is a tungsten-based alloy doped with lanthanumoxide. The content of La2O3 is 1 weight%. The structure and therefore the properties depend strongly on the material deformation ratio.
Advantages compared to pure W:
- better creep resistance
- higher recrystallization temperature for high deformation ratio
- better high-temperature strength
- better machinability
Advantages compared to WT20 (for applications as an electrode material):
- not radioactive
- maximum emission rate at lower temperatures
- lower burn off-rate of the electrodes
Typical areas of application:
- components for the manufacture of quartz glass
- electrodes for discharge lamps in the lighting industry
- TIG welding electrodes
- components for ion implantation
