PURPOSE:To improve the brazability of an iron alloy used as a lead material for a ceramic package type lead which undergoes brazing by specifying the amounts of Ni, Co, Si and Fe. CONSTITUTION:This iron alloy for a lead material has a composition consisting of 25-34% Ni, 14-20wt% Co, 0.3-1wt% Si and the balance Fe. The iron alloy shows superior brazability when used as a lead material for a ceramic package type which undergoes brazing.
