Description

Tungsten is doped with lanthanum oxide and zirconium oxide to obtain high creep resistance coupled with a low electron work function. WLZ has very good ignition properties and remains stable even at extremely high temperature ranges.

This material data has been provided by Plansee.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
