Abstract (en)

[origin: WO8910417A1] A contact material contains silver and at least one metal, metal alloy or metallic compound having a higher melting point than silver. According to the invention, the material contains, in addition to silver (Ag), from 2 to 50 % of at least iron (Fe) and/or titanium (Ti). It may also contain nitrides, carbides and/or borides of the metals titanium, zirconium and/or tantalum. The material possesses a spectrum of contact properties essentially identical to that of AgNi10, and can completely replace the latter.
