Abstract

Abstract PURPOSE:To obtain an alloy for a spark plug excellent in oxidation resistance and workability by specifying a compsn. constituted of Si, Cr, Mn, Al and Ni. CONSTITUTION:This is an alloy for a spark plug contg., by weight, 1.0 to 2.5% Si, 0.5 to 2.5% Cr, 0.5 to 2.0% Mn and 0.6 to 2.0% Al, furthermore contg., at need, 0.005 to 0.1% rare earth elements and the balance substantial Ni with inevitable impurities. The alloy has the characteristics in which oxidation resistance is moreover improved to satisfactorily correspond to the high performance and high loading of an internal combustion engine as well as relatively good workability.
