Abstract
A survey is given of the various types of contact materials presently produced in Europe for application in vacuum switchgear. The materials discussed comprise tungsten-base and molybdenum-base materials, as well as copper-iron and copper-chromium materials. The production techniques currently practiced are described, and the resulting properties of the materials are discussed with regard to the requirements of the different types of application.Keywords
