Small cars often use aluminum alloy single cylinder or multi cylinder cast iron cylinder heads, and there are two mainstream cylinder head materials.
Advantages of aluminum alloy cylinder head:
1.self ignition performance, and can still ensure high strength and toughness under high temperature conditions;
2.Good thermal conductivity, which can lower the temperature of the engine;
3.Low friction coefficient can improve efficiency and reduce wear.
4.For design requirements such as aesthetic appearance, low deformation shrinkage rate, and excellent processing fluidity required by manufacturing processes, etc

Advantages of cast iron cylinder heads:
1.High mechanical strength and good casting performance.
2.High temperature resistance, high pressure resistance, oxidation resistance, and friction resistance.
3. Stable combustion chamber: As a part of the engine combustion chamber, the cast iron cylinder liner of the car has a stable combustion chamber shape, which can ensure the normal operation of the engine.
4. Wide adaptability: Cast iron cylinder sleeves for automobiles are suitable for various types of engines, including gasoline engines, diesel engines, and turbocharged engines.
5. Easy to process and manufacture: The material of cast iron cylinder sleeves for automobiles is easy to process and manufacture, and can be produced in large quantities, reducing production costs.
6. Low maintenance cost: Due to the good wear resistance and corrosion resistance of cast iron cylinder sleeves in automobiles, their maintenance cost is relatively low.
