Description

WVM is pure tungsten doped with a tiny amount of potassium. This doping, which also interacts with the highly orientation-dependent cold working, creates a stacked microstructure which results in increased dimensional stability at high temperatures.

This material data has been provided by Plansee.

All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
