Recycling Iridium Spark Plugs for Sustainability

Recycled iridium from spark plugs is reused in new plugs or industrial catalysts, conserving non-renewable resources and reducing environmental impact. DONGSHENG offers high-value bulk recycling for iridium plugs from auto workshops/scrapyards with fast payment processing.

Electrode Materials

Center Electrode: Iridium alloy (melting point 2454°C, hardness 240 kgf/mm² ≈2400 HV).

Ultra-fine 0.4mm diameter enhances ignition precision.

Ground Electrode: Platinum-tipped or tapered cut designs reduce quenching effect and improve spark stability.

Performance Specifications

Gap: 0.8–1.1mm

Heat Range: 5–6

Lifespan: 60,000–100,000 km

Core Benefits

Powerful Ignition: Ultra-thin electrode focuses spark energy, improving cold starts and reducing idle vibration.

Eco-Efficiency: Complete combustion cuts fuel consumption and lowers CO/HC emissions by 25%.

High Durability: Resists extreme heat corrosion, ideal for turbocharged and high-RPM engines.
