What materials are generally used for heavy truck castings?

Heavy-duty truck castings are a key component of the truck, and their quality and performance directly affect the safety, reliability and service life of the truck.

Heavy-duty truck castings generally require high wear resistance and good mechanical properties. This is because heavy-duty trucks weigh more than other trucks and have higher requirements for castings. The two common casting materials are alloy cast iron and steel castings. These two materials are slightly different, but both have good wear resistance.

Alloy cast iron is composed of iron, carbon, silicon, manganese and other elements. Its advantage is that it has a uniform structure. This alloy cast iron performs well under heavy load and high-strength conditions, and can meet the strength and strength requirements of heavy-duty trucks. Wear resistance requirements.

Steel castings have superior mechanical properties. Steel castings are usually made of alloy steel or carbon steel. Through precise smelting and casting processes, this casting has excellent tensile strength, compressive strength and corrosion resistance. This makes steel castings critical components for heavy-duty trucks, such as engine mounts, suspension systems, and more.

Since heavy-duty trucks are subjected to harsh environmental and working conditions during transportation and work, castings need to have good fatigue resistance. The characteristics of alloy cast iron and high-strength steel castings allow them to withstand long-term, high-intensity workloads.
