Material selection
Cast aluminum alloy: Lightweight and with excellent thermal conductivity, it is suitable for gasoline engines, which can increase the compression ratio and reduce local overheating.
Cast iron or alloy cast iron: It has strong high-temperature resistance and creep resistance, and is suitable for the high-pressure environment of diesel engines.
Composite materials: Future trend, featuring lightweight, high-temperature resistance and corrosion resistance.
Material performance standards
The hardness requirements (HBW≥80) and mechanical properties (such as tensile strength) must comply with industry standards to ensure the stability of the cylinder head under high temperature and high pressure.
Cast aluminum alloys need to undergo tests such as grain size and microscopic porosity to avoid internal defects.
