Iridium Alloy Chips for Spark Plugs
Able to withstand the corrosion and heat of harsh environments, iridium alloy helps extend the life of spark plugs.
Within the cylinders of an engine, the heart of an automobile, a mixed gas of compressed gasoline and air is repeatedly ignited and combusted. Iridium plays an important role as the tip electrodes of the spark plugs within this harsh, high-temperature environment.
