Tungsten is improved by the high-temperature properties and corrosion resistance of molybdenum. The molybdenum tungsten alloy is available in different compositions from MW20 with 20 percent tungsten by weight to MW50 with 50 percent tungsten by weight.

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.
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.

Application areas

MoW materials are primarily used for the manufacture of zinc as well as for stirring tools in the glass industry. In addition, MoW alloys are used to produce sputtering targets for coating flat screens. MoW layers possess enhanced etchability, a property which is of value for the manufacture of thin-film transistors.
