Product Description
Automobile crankshaft pulley is an important part in the engine, which is used to transmit the power between crankshaft and camshaft. Its materials are usually as follows:
1. Aluminum alloy: Aluminum alloy is a common material of crankshaft pulley, which has the characteristics of light weight, corrosion resistance and good thermal conductivity. Aluminum alloy crankshaft pulley is usually subjected to precision machining and surface treatment to improve wear resistance and durability.
2. Steel: Some cars use crankshaft pulleys made of steel, which has high strength and hardness and is suitable for working environment with high pressure and high speed.
3. Cast iron: Cast iron crankshaft pulley is still used in some old models. Cast iron has high wear resistance and durability, but it is relatively heavy.
4. Polymer composite material: In recent years, some high-performance cars began to use polymer composite material to manufacture crankshaft pulleys, which has excellent wear resistance and corrosion resistance.
Choosing the material of crankshaft pulley needs to be considered comprehensively according to the vehicle model, engine performance requirements and service environment. Different materials of crankshaft pulley have different characteristics and application scope, so it is necessary to select the crankshaft pulley material that meets the vehicle requirements and performance requirements to ensure the normal operation and safety of the engine. It is suggested that when replacing the crankshaft pulley, the original accessories or brand-recognized crankshaft pulley should be selected to ensure stable quality and performance.
