Why Are Iridium Spark Plugs So Expensive?

Iridium spark plugs are known for their exceptional performance, durability, and longevity. However, they are also more expensive than other types of spark plugs. At Dingfeng Precious Metals, we understand the value of iridium and specialize in recycling this rare metal from used, damaged, and scrap spark plugs.

Why Iridium Spark Plugs Are Expensive

1. Rarity of Iridium

• Iridium is one of the rarest metals on Earth, making it difficult and costly to obtain. It is estimated to be about six times rarer than platinum.

• Mining and refining iridium require complex processes, adding to its high cost.

2. High Melting Point

• Iridium has an exceptionally high melting point of 2450 °C (4442 °F), allowing it to withstand extreme temperatures and harsh combustion conditions.

• This heat resistance contributes to the longer lifespan and superior performance of iridium spark plugs, but it also makes the manufacturing process more challenging and expensive.

3. Manufacturing Process

• To create iridium spark plugs, manufacturers use fine-tipped electrodes to improve ignition efficiency.

• The process of bonding or welding iridium tips onto electrodes is technically demanding and requires precision machinery, increasing production costs.

4. Durability and Performance

• Iridium spark plugs are designed to last up to 120,000 miles or more, which is significantly longer than copper or even platinum plugs.

• Their durability and superior performance justify the higher price, as they provide better fuel efficiency, smoother acceleration, and improved ignition reliability.

5. Market Demand

• Many modern vehicles require iridium plugs for optimal performance, increasing their demand and affecting pricing.

6. Recycling Value

• Due to the value of iridium and other precious metals, used iridium spark plugs have considerable recycling value. At Dingfeng Precious Metals, we recover iridium, platinum, palladium, and other valuable metals from used plugs, contributing to sustainability and cost-effectiveness.

The Role of Recycling

Recycling iridium from spark plugs is essential for reducing costs, promoting sustainability, and ensuring a stable supply of this precious metal. At Dingfeng Precious Metals, we utilize advanced processes to extract iridium and other valuable materials from discarded spark plugs, contributing to a cleaner and more efficient industry.
