铜的核心镍化合物的中央电极

The copper core-nickel compound central electrode is the key part of the spark plugs. It has features such as wide heat range, good heat and electricity conductivity, resistance to oil fouling and carbon deposits, and energy efficiency.This central electrode is widely used in spark plugs to ensure stable ignition, and compared with the nickel central electrode, the heat range can be increased by 20 30%. The material used for the central (copper and nickel alloy) electrode conforms with the standard DIN and National Machinery Co., Ltd. guidelines. The production processes are controlled based on VDA 6.1 quality assurance system guidelines
