* Aluminum: Lightweight, strong, and good at dissipating heat, making it ideal for engine blocks and cylinder heads.
* Iron (Cast Iron): While less common in modern engines, it's still used for components like engine blocks, cylinder liners, and crankshafts. It's strong, durable, and cheaper than aluminum.
* Steel: Used for various engine components like connecting rods, camshafts, and valves. It offers strength and wear resistance.
* Other Alloys: Many other metals and alloys are used in smaller amounts for specific components, including:
* Copper: For bearings and cooling system parts.
* Magnesium: For lightweight parts like valve covers and engine casings.
* Titanium: Used in high-performance engines for lightweight components like valves and connecting rods.
The specific metals used in an engine can vary depending on factors like the engine size, type, and the vehicle's intended purpose.
