Which material is the best for spark plugs

The best material for spark plugs depends on the specific application requirements and engine type. It plays a vital role in the ignition system of gasoline engines. It is responsible for introducing high-voltage current into the cylinder to generate electric sparks, thereby igniting the combustible mixture. Iridium platinum spark plug is a common high-performance spark plug. Its center electrode uses iridium to improve ignition performance, while the side electrode uses platinum to ensure long life and stability.

Common materials for spark plugs include nickel alloy, platinum, iridium, etc. Each material has its specific application scenarios and advantages. For example, nickel alloy spark plugs are more economical and suitable for general purposes; platinum spark plugs are known for their long life and stability and are suitable for harsh working environments; iridium spark plugs are characterized by their excellent ignition performance and high durability and are suitable for High performance engine.

Spark plugs In terms of spark plug selection, dual iridium spark plugs and iridium platinum spark plugs are two common types. The main difference between them is that the materials of the central electrode and side electrodes are different:

1. The spark plug is made of iridium and platinum. The central electrode and side electrode of the double iridium spark plug are mainly made of iridium. Therefore, the double iridium spark plug has the characteristics of high hardness, high corrosion resistance and high melting point. Therefore, the service life of the double iridium spark plug is also the longest among all spark plugs. longer.

2. NGK double iridium is better. The center electrode and side electrodes of NGK Dual Iridium are made of iridium. Due to the characteristics of high hardness, high corrosion resistance and high melting point, NGK double iridium spark plugs have the longest service life, up to 100,000 kilometers.

3. Dual-iridium and iridium-platinum each have their own advantages: Dual-iridium spark plugs have good performance and are moderately priced, but have a short service life, generally 30,000-40,000 kilometers; platinum spark plugs are slightly more expensive but have a long service life, nominally 100,000 kilometers.

4. Dual-iridium and iridium-platinum each have their own advantages.

Platinum spark plugs are slightly more expensive but have a long service life, nominally 100,000 kilometers.
