DONGSHENG Aviation Spark Plug Recycling

After bulk collection of aviation spark plugs, DONGSHENG extracts iridium/platinum from end-of-life units using advanced separation technology. Recycled platinum-iridium metals are reused in new aviation plugs or aerospace components. We serve airlines/MRO facilities with bulk recycling programs for expired spark plugs.

Aviation Spark Plug Key Specifications

Electrodes: Iridium/platinum center electrode, nickel-chromium alloy shell for corrosion resistance

Gap: 0.5–0.8mm

Voltage Resistance: Withstands over 20,000 volts

Lifespan: 300-500 flight hours

Core Functions

Ultra-High Reliability: Redundant dual-ignition system ensures operation during single-side failure

Extreme Environment Tolerance: Operates at -50°C to 2000°C (prevents icing at altitude/high-temperature erosion)

RF Interference Suppression: Special ceramic resistors eliminate spark noise, protecting avionics
