Which Car Part is Made of Tungsten Steel?
2 Answers
Strictly speaking, there isn't one, but certain components may have similar coatings, such as the molybdenum coating on piston rings and the molybdenum coating on transmission synchronizers. However, tungsten steel tools are extensively used in the automotive manufacturing process, such as stamping dies for parts, and various turning, milling, and cutting tools for components. Main advantages: Tungsten steel materials are entirely made of high-quality tungsten steel, which is extremely hard but brittle, making it prone to fracture under external impact, especially for thin tungsten steel cutting blades that are more susceptible to shattering under force. Therefore, when installing and using various tungsten steel materials, it is prohibited to strike or throw them.
I grew up helping my dad repair cars and have an in-depth understanding of automotive components. In vehicles, tungsten steel is most commonly used in the ignition electrodes of spark plugs. This material has exceptional hardness, enabling it to withstand high temperatures and friction inside the engine, ensuring more stable ignition. If the electrodes are severely worn, the car may experience shaking, difficulty starting, or even increased fuel consumption. I remember repairing an old Volkswagen that broke down midway due to aged spark plugs – after replacing them with new ones featuring tungsten steel electrodes, it ran smoothly immediately. During routine maintenance, I always remind car owners to inspect their spark plugs every 30,000 kilometers. Don’t underestimate this step; otherwise, repairs could cost an extra thousand bucks. Additionally, in some high-performance cars, tungsten alloy might be blended into clutch plates for enhanced durability, but spark plugs remain the common choice for mass-market models.
