For production technology, we use Japanese cold sealing to process middle and high-end spark plugs and Denso hot sealing to produce spark plugs with competitive prices. There are 23 mechanics and 2 senior mechanical designers in our spark plugs R&D department. Besides, the perfect quality inspection equipment and one 8-person quality control team are adopted to ensure zero defective products.
Our product range covers iridium spark plugs, double iridium plugs, nickel copper standard spark plugs, platinum spark plugs, single-electrode spark plugs, multi-electrode spark plugs, and our self-developed two-low-one-high three-electrode iridium spark plugs. Our spark plugs are widely applied for automobiles, motorcycles, generators and small machinery.

About Spark Plugs

What is a Spark Plug Made Of?
A spark plug is made of terminal nut, insulator, center electrode, ground electrode (or side electrode), metal housing, seals and gaskets, etc. Here's a breakdown of the main components and the materials commonly used in spark plugs:

1.Terminal nut: This is where the spark plug wire or coil boot is attached. The terminal receives the high voltage current from the ignition coil.
2.  Insulator: It is the most important part of a spark plug and serves to isolate the electrical charge and heat generated by the spark. It is typically made of a special ceramic material that can withstand high temperatures and electrical stress. Alumina (aluminum oxide) is a common ceramic material used for this purpose due to its excellent insulating properties and high thermal stability.
3. Center Electrode: It protrudes into the combustion chamber and generates the spark. It is usually made of a high-conductivity metal such as copper, nickel, platinum or iridium. Copper is commonly used in standard spark plugs due to its excellent electrical conductivity, while platinum and iridium are used for middle-high end vehicles for their superior durability and resistance to erosion.
4. Ground Electrode: It is integrated with the housing and opposites to the center electrode. Like the center electrode, it is typically made of a high-conductivity metal such as nickel or platinum.
5. Metal Housing: It surrounds the insulator and provides mechanical support and electrical grounding for the spark plug. It is usually made of steel.
6. Seals and Gaskets: Spark plugs often include seals and gaskets made of materials such as rubber or silicone to prevent leakage of combustion gases and engine fluids.
7. Hexagon: Steel shell where a socket wrench fits for tightening or loosening the plug.
8.  Corrugations or Ribs: It stops voltage from jumping to the hex head.

Types of Car Spark Plugs

Car Spark plugs vary in electrode material, number of ground electrode, and car fuel. There are normally 6 kinds of spark plugs by electrode material, that is, nickel copper, platinum, iridium, double platinum, iridium platinum and double iridium spark plugs. 
Nickel Copper Spark Plugs:
Nickel copper is the basic material for the center electrode. As nickel and copper have relatively low melting points, which means that the edge of these electrodes wears quickly, resulting in an increased gap in as little as 20,000 kilometers. So it has a short lifespan, somewhere around 30,000 kilometers. 
Platinum Spark Plugs
Platinum plugs use a platinum disc that is soldered to the end of the center electrode, which allows the plug to last longer than a copper plug, retaining its edge better, which means better conductivity. Platinum spark plugs tend to run hotter, preventing fouling and buildup of deposits. And the lifespan of platinum spark plugs is around 50,000 kilometers. 
Iridium Spark Plugs
It has iridium disc welded in the end of center electrode. Iridium is harder than platinum and has an even higher melting point (4,442º F), which allows these spark plugs to last about 20% longer than platinum spark plugs. They are designed to offer superior performance, longevity, and reliability compared to traditional spark plugs. They can work at least 60,000 kilometers when installed in naturally aspirated cars. 
Double Platinum Spark Plugs
A double-platinum plug has a platinum disc on both the center electrode, and the side electrode. This created a plug that is very durable, lasting upwards of over 80,000 kilometers in naturally aspirated cars. 
Iridium Platinum Spark Plugs
An iridium platinum plug means that there is iridium disc welded on the center electrode, and platinum disc on the side electrode.Usually this type of spark plugs are designed for turbocharged vehicles.The working life can be high as 100,000 kilometers. 
Double Iridium Spark Plugs
Double Iridium spark plugs are the type which have iridium disc on both the center electrode, and the side electrode. They are designed to deliver the firepower necessary under any driving conditions, especially extreme heat or continual high-speeds, and can provide up to 4 times the normal life of service compared to a standard copper spark plug. 
Here is a chart to summarize the 6 types of spark plugs.
