Driving a light and fast car has become the idea of many consumers. Automobile lightweighting is also the goal pursued by the major automobile manufacturing industries today. Under the premise of ensuring the strength and safety performance of the automobile, the weight of the entire automobile is reduced as low as possible, thereby improving the dynamics of the automobile, reducing fuel consumption, and reducing exhaust pollution. After continuous exploration by car manufacturing experts, we finally found a high-quality material for making light and light cars-aluminum.
This is why in recent years, many automobile manufacturers (such as BMW, Mercedes-Benz, Tras, etc.) have begun to use aluminum metal in automobile production. Because the weight of aluminum is much lighter than steel and iron, and aluminum can be made into aluminum alloy with other metal materials, its hardness can also be comparable to steel, so there is no need to worry about the safety performance of cars made of aluminum.
For the use of aluminum metal in the automobile manufacturing industry, it is currently mainly used in four aspects: car body, wheel hub, engine and air conditioning in the car.
The main body of the car body is 2000 series, 5000 series and 6000 series aluminum alloy, and some car manufacturers use 7 series aluminum alloy (usually used in aircraft landing gear or high strength parts of fighter fuselage).
The wheel hub is mainly made of ALSi series alloy, Mg alloy, 6061 deformed aluminum alloy.
The engine is the core of the car, and its cylinder block uses die-cast aluminum alloy. At present, the engine block of some cars cannot be replaced with cast aluminum, and cast iron is still used.
The vehicle air conditioner is changed to an automobile aluminum heat exchanger, which is composed of an aluminum tube that passes cooling water and an aluminum fin that functions as a heat sink.
Please do not prejudice aluminum cars, think that aluminum cars are not safe, because lightweight cars made of aluminum alloys are the future development trend of the entire automotive industry and car users.
