Abstract (en)
[origin: WO9222079A1] The material used for contacts in low-voltage switches, in particular, consists of silver and other active components. The invention calls for a combination of iron (Fe) present in a proportion between 1 and 50 % by wt. and rhenium (Re) in a proportion between 0.01 and 5 % by wt. The material can be produced and the contacts fabricated using powder-metallurgy methods, together with moulding or extrusion techniques, the active components being used in the form of separate powders, as a fusible alloy or as a mechanically alloyed powder.
