piston alfin ring for casting Aluminum piston wear-resistant ring

Descripción del producto

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 **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.
