In order to reduce fuel consumption and CO2 emissions, the lightweight of automobiles has become one of the focuses of attention. Reducing the weight of the car engine, reducing fuel consumption, and achieving energy saving and emission reduction, the aluminum alloy launching level has become a new choice for major enterprises.
The advantage of the aluminum alloy engine is that it is light in weight, effectively reduces the engine's own weight, and has good heat dissipation. In addition, the manufacturing process requires a slightly higher cost, and the manufacturing cost is more expensive than that of the cast iron engine. The disadvantage is that the engine is easily deformed by heat during operation, and the gap between the inner wall of the cylinder and the piston becomes larger under long-term operation, and the power leakage is large. In addition, aluminum alloy engines must not over-press the engine's power. However, with the improvement of technology, the high temperature resistance of aluminum alloy engines is not worse than that of cast iron.
The aluminum plate for engine can be selected from 5454 aluminum plate. The 5454 aluminum plate has high strength, high corrosion resistance, good plasticity and good molding processability. The strength of 5454 aluminum sheet is about 20% higher than that of 5052 aluminum plate. 5454 aluminum plate is also widely used in pressure vessels. , marine facilities pipelines, car wheels, tank car bodies.
