SILVER-BASED CONTACT MATERIAL FOR USE IN POWER-ENGINEERING SWITCHGEAR, AND A METHOD OF MANUFACTURING CONTACTS MADE OF THIS MATERIAL

摘要

in particular, for parts of contact in low voltage switches, the contact material is silver and the other active components. according to the invention, the active components are a mixture of iron oxide (fe2o3 and fe3o4) ratio ranging from 1 to 50% by mass of at least one of an oxide and other chemical element in proportion to concentration ranging from 0.01 to 5%.in particular, the constitution of agfe2o3reo2 contact materials and agfe2o3zro2 have proven their value in practice. the manufacture of the material and manufacture of contact parts can be done by methods of powder metallurgy, including the method of casting or extrusion.
