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
