In addition to special steel, key components of engines may also use the following materials: Cast iron: Cast iron is a common material for engine components, mainly used for manufacturing cylinder blocks, cylinder heads, and other components. Cast iron has high thermal stability and good mechanical properties, which can withstand high temperature and high pressure environments during engine operation. Aluminum alloy: Aluminum alloy is commonly used in the manufacturing of engine cylinder heads, pistons, and other components due to its lightweight and good thermal conductivity. Aluminum alloy materials can reduce the weight of engines, improve fuel economy, and have good corrosion resistance. Titanium alloy: Titanium alloy is a high-performance material with high strength, low density, and good heat resistance. In engine components, titanium alloy can be used to manufacture components in high-temperature areas, such as turbocharger blades and shafts. Ceramic materials: Ceramic materials have excellent high-temperature resistance and wear resistance, and can be used in certain key components of engines, such as valve seats, combustion chambers, etc. The use of ceramic materials can improve the thermal efficiency and durability of engines. Composite materials: Composite materials are composed of two or more materials with different properties, which have excellent mechanical properties and temperature resistance. In engine components, composite materials can be used to manufacture complex structural components, such as intake manifolds, fuel injectors, etc. It should be noted that the material selection of engine components depends on the specific application scenario and requirements. Different materials have their own advantages and limitations, therefore, in the process of engine design and manufacturing, it is necessary to comprehensively consider factors such as the working conditions, performance requirements, and economy of the components.
