A sintered Ag-Fe material consists of (in wt.%): 0.5-20 Fe; 0-5 Zn, Cu, Mn, Re, Ir, Ru and/or oxides of W, Mo, Zn, Al, In, Si, Zr; balance Ag with the Fe contg. >0.25% C. The amt. of carbon in the Fe is pref. >0.4, esp. 0.6-1.2%. The material is made by mixing together the starting powders in the amts. prescribed, cold isostatic pressing, sintering at 650-940 deg C and then extruding. The sintering is carried out in a hydrogen-free protective atmosphere. |
