1. aluminum cylinder block and cylinder head

Considering that automobile engines and cylinder heads are required to have good thermal conductivity and corrosion resistance, and aluminum alloys happen to meet these requirements, many automobile manufacturing companies mostly use all-aluminum steel sleeves.

 

2. aluminum radiator

Today aluminum products are also used in condensers and evaporators of heat exchangers and oil coolers, such as automotive air conditioners, including radiators and heaters. The aluminum radiator mainly considers durability and heat dissipation ability.

 

3. aluminum alloy wheel hub

The wheel is an important safety component and requires high safety requirements. Various types of aluminum alloy wheels are widely used in automobiles. Aluminum alloys for wheel rims require high strength (fatigue strength, flash weldability, roll formability); aluminum alloys for casting require good workability and sufficient strength.

According to statistics, the utilization rate of aluminum alloy wheels has been about 50%, and in some countries it has exceeded 60%. In order to meet the requirements of automobile lightweight, aluminum wheels are moving towards thinner thickness, more complex shapes, lighter and safer development trajectory. Aluminum wheels have better heat dissipation, effectively avoiding overheating of tires and extending their service life. In addition, from the point of view of processing, aluminum wheels have high dimensional accuracy, which reduces vibration during driving and improves the comfort of the car.

 

4. aluminum bumper

Bumpers have been widely installed on automobiles as a buffer to absorb impact energy. However, the installation of the bumper invisibly increases the weight of the car itself. Considering that the safety factor of the aluminum bumper is higher than that of the plastic material, it is more durable.

 

5. aluminum body

The essence of the automobile industry is the production of automobile bodies, which account for about 60% of the total cost of automobile construction.

As the most important component of the car, the car body is also an important part of the quality, so its light weight is of great significance to the total weight of the car. Nowadays, automobile enterprises are developing and researching aluminum alloy and all-aluminum body, and have achieved certain results.

6. chassis components

In terms of reducing vehicle mass, nothing has more potential and is easier to achieve than a chassis system. Aluminum is an alternative to steel in suspension systems.
