Why Iridium Spark Plug Recycling Matters: Insights from Dingfeng Precious Metals

Iridium is one of Earth’s rarest elements—only 8 tons are mined annually. Yet, its use in high-performance iridium spark plugs (found in 70% of modern vehicles) makes recycling essential.

Unique Properties

• Melting Point: 2,466°C (ideal for spark plug electrodes).

• Durability: Iridium plugs last up to 120,000 miles.

Mining vs. Recycling

• Mining 1 kg of iridium produces 10,000 kg of waste rock.

• Recycling recovers iridium at 1/10th the environmental cost.

Applications Beyond Automotive

• Medical: Used in pacemakers and radiation therapy devices.

• Aerospace: Critical for satellite components.
