  • Spark plug copper core alloy
    Patent number: 6677698
    Abstract: A spark plug electrode is disclosed. The electrode comprises, based upon the total weight of the electrode, about 83 wt. % to about 96.8 wt. % copper, about 3.0 wt. % to about 9.0 wt. % chromium, and about 0.2 wt. % to about 8.0 wt. % niobium. A spark plug is also disclosed. The spark plug comprises a shell disposed in contact with an insulator body. A center electrode is disposed at a lower end of the insulator body. A side electrode is also disposed at a lower end of the shell. This side electrode is coaxially aligned with the center electrode. At least one of the center electrode and the side electrode comprises a core composition of about 83 wt. % to about 96.8 wt. % copper, about 3.0 wt. % to about 9.0 wt. % chromium and about 0.2% to about 8.0% niobium, based upon the total weight of the composition. A resistor section is also disposed in electrical communication with the center electrode.
