Abstract
To improve high-temperature strength, as well as increased resistance to wear due to sparking, a Ni-based alloy sparking plug electrode material for use in an internal combustion engine is provided. Such a Ni-based alloy sparking plug electrode material contain, by weight, from 3.1 to 4.3 of Al, from 0.5 to 1.5% of Si, from 0.45 to 0.65% of Mn, from 0.002 to 0.01% of C, from 0.005 to 0.05% of at least one of Mg and Ca, and, as necessitated, from to 2% of Cr, with the balance substantially Ni and inevitable impurities.
Claims2
A Ni-based alloy sparking plug electrode material for use in an internal combustion engine, comprising:
- a Ni-based alloy containing, by weight percent;
- from about 3.1 to 4.3% of Al;
- from about 0.5 to about 1.5% of Si;
- from about 0.45 to about 0.65% of Mn;
- from about 0.002 to about 0.01% C;
- from about 0.005 to about 0.05% of at least one element selected from the group consisting of Mg and Ca, whereby said at least one of Mg and Ca are effective when present with Si;
- and
- a balance consisting substantially of Ni and inevitable impurities.
