Product Application: Used in the first groove of aluminum pistons in internal combustion engines, initially applied to diesel engine aluminum pistons, with wear-resistant insert rings widely used and promoted on gasoline engine aluminum pistons in recent years as industry demands for gasoline engine pistons have increased. Features: Compared to traditional aluminum pistons, pistons with insert rings have seen an average increase in lifespan of 5-8 times, enhancing energy utilization and combustion efficiency, while reducing emissions. Additionally, it significantly improves the performance and reliability of internal combustion engines. Material: The wear-resistant insert rings are made of high-nickel austenitic cast iron, while aluminum pistons are typically made of silicon-aluminum alloy. Their similar coefficients of expansion form the basis for the application of wear-resistant insert rings in the first groove of pistons. Wear Resistance: High-nickel austenitic cast iron exhibits outstanding wear resistance, optimizing friction with piston rings at high temperatures, thereby increasing piston lifespan. Thermal Conductivity: The material boasts excellent thermal conductivity, facilitating heat transfer and dissipation to maintain piston head temperature within a reasonable range. Corrosion Resistance: Strong corrosion resistance enables adaptation to various working environments, ensuring stability under different conditions. Environmental Friendliness: Prolonging piston lifespan ensures combustion chamber sealing during piston operation, enhancing combustion efficiency, and reducing exhaust emissions. Precision Machining: Precise machining techniques during manufacturing ensure products meet design requirements, enhancing performance.
