    Cixi Tongxin Auto Parts Co., Ltd. currently offers spark plugs with multi-side electrode spark plugs, V-groove center electrode spark plugs, sheet metal spark plugs, platinum spark plugs and patented spark plugs. NPL-resistant Pudong gold spark plug series is one of the company's current series of products, featuring rapid ignition, fuel-saving and power-saving.

    The wider variety of spark plugs nowadays is mainly sheet metal spark plugs and platinum spark plugs.

    The sheet metal in the sheet metal spark plug is a very expensive rare metal. Spark plugs made with it generally have the following characteristics:

    First, the combustion state comparison: Compared with the ordinary spark plug, the sheet metal spark plug has a fast flame diffusion, effectively improves the combustion efficiency, reduces the formation of carbon deposits and exhaust gas emissions, and saves fuel consumption to a certain extent.

    Second, the superior acceleration performance: sheet metal spark plug, because the extremely thin sheet metal electrode improves the electrical boundary strength, even at low voltage can produce a more powerful spark.

    Third, the engine is easier to start: extremely high ignition performance and low ignition voltage, thereby reducing the misfire in the case of low ignition voltage and the unexpected flameout of the engine caused by the bad ignition environment.

    Fourth, long life: the life of ordinary resistance spark plug is 20,000 kilometers, and the service life of sheet metal spark plug can reach 8 to 90,000 kilometers, which is 4-5 times that of ordinary spark plug.

    The difference between platinum spark plugs and sheet metal spark plugs:

    The difference between sheet metal spark plugs and platinum spark plugs is that the electrode materials are different. Both bismuth and platinum are rare metals, have a higher melting point, and can maintain a stable working condition under the high temperature conditions of discharge and combustion. But sheet metal spark plugs and platinum spark plugs are very different.

    The melting point of sheet metal is higher than that of platinum. Under high temperature conditions, the sheet metal spark plug can maintain a more stable ignition effect. At the same time, due to the high melting point of the sheet metal spark plug, the center electrode can be made thinner, the ignition voltage is required to be lower, and the discharge performance is also improved. Platinum has a lower melting point than sheet metal, but under normal conditions, platinum spark plugs also perform well, and platinum spark plugs pursue stable performance. Under normal conditions, the life expectancy can be as high as 100,000 kilometers.

    The hardness of tantalum is much higher than that of platinum, so the durability of the sheet metal spark plug is higher, and the spark plug life will be longer than that of the platinum spark plug.

    In addition, the sheet metal spark plug has a faster ignition speed than the platinum spark plug, and the engine with a sheet metal spark plug will have a better acceleration effect.

    The cost of sheet metal spark plugs is high and the price is correspondingly higher. Under normal conditions, the price/performance ratio of platinum spark plugs has a great advantage.

    On the whole, the overall performance of the sheet metal spark plug is superior to that of the platinum spark plug, but the price/performance ratio of the platinum spark plug also has a great advantage. It is recommended that you choose the spark plug according to your individual needs.
