Abstract (en)
[origin: US4948424A] Sinter contact materials produced from an intraoxidized alloy powder having the constitution AgSnO2Bi2O3CuO have added thereto at least zirconium oxide and optionally additionally bismuth oxide in parts by weight of preferably between 0.1 and 5%. For the production of these materials, zirconium oxide power and optionally additionally bismuth oxide powder is added to the intraoxidized alloy powder AgSnO2Bi2O3CuO. With such a contact material, the excess temperature behavior in motor contactors is improved.
