囲内に限定される。In the spark plug discharge electrode material used in the present invention, Cr is an element that improves high-temperature oxidation resistance and lead corrosion resistance, and the effect is small when the content is less than 14% by weight, and when the content is less than 18% by weight. This results in poor workability (in addition, in the present invention, A7 is an element that improves high-temperature oxidation resistance, and 0.
If it is less than 0.05% by weight, the effect will be small, and if it is more than 0.5% by weight, the processability will deteriorate, so it is limited to a range of O,OS to 0.5% by weight. Since S significantly deteriorates the high temperature strength of the Ni-based alloy, the content is limited to 0.015% by weight or less. S+ is an element that improves high-temperature oxidation resistance and lead corrosion resistance in the alloy of the present invention, and when the content is less than 0.1% by weight, the effect is small, and when it is added more than 0.5% by weight, it improves workability. Since it causes deterioration, it is limited to a range of 0.1 to 0.5% by weight.
