Abstract: Induction-type reaction rail which can be easily shaped and welded and has a high electrical resistance, for use in conjunction with linear motors which power high speed trains, being made out of an alloy with the composition 0.7-3.5 % Mn rest aluminium which has a purity of at least 99.5 % in particular with an maximum impurity content of 0.1 % Fe and 0.15 % Si. For the production of induction-type reaction rails the alloy is rapidly cooled from the melt by continuous casting then heated to a temperature of 300*-500*C prior to extrusion and then extruded to shape and the emerging section rapidly cooled.
