On the other hand require excellent thermal conductivity of the spark plugs, if not timely dissemination of the heat out, ranging from the impact on engine power, and if the engine knock even as a fuel, thereby damage the engine. Based on the improvement of thermal conductivity properties, INCONEL 600 nickel electrode, double copper electrode spark plugs and long thread has become a trend.

Spark Plug heat transfer about 63% through the center electrode sealed gasket shell and center electrode thread sealing gaskets, and 20% through the centre electrode way of sealing gaskets conduction out, we can see that the thermal conductivity electrode how important. INCONEL 600 nickel alloy is a nickel - Chrome - iron-based solid solution strengthening alloy, it is applied in the spark plug, a high temperature corrosion, and other excellent antioxidant properties, the thermal conductivity INCONEL 600 ordinary nickel alloy is 11 times about it than ordinary nickel alloy electrode spark plugs more erosion resistant to extend the life of a spark plug, is a novel, the spark plugs, environmental protection, energy conservation products.
