What Spark Plugs Are Made Of
Spark plugs are small but complex. They are typically made of a combination of:
- Ceramic Insulators: Providing electrical insulation and heat resistance.
- Metal Casings: Often nickel-plated steel.
- Precious Metal Tips: Some high-end spark plugs feature platinum or iridium tips, which are highly valuable for scrap.
Why Some Spark Plugs Have Value
Not all spark plugs are created equal. The key to their value lies in the materials used, especially the precious metals:
- Platinum or Iridium Tips: These metals are worth more than typical scrap steel, making certain spark plugs far more valuable.
- Copper Tips: These “flatter” tips may look enticing, but are simply worth the scrap steel as there is very little copper.
- Steel Casings: Even without precious metals, the metal casing can be recycled for its scrap value.
