[Alcoa.com] Now that many owners are repairing their cars, they are not repairing their old injuries and new injuries have emerged. So what should pay attention to the maintenance of automotive aluminum body? Today, this article will tell the owners about automotive body maintenance and precautions.
In our lives, many owners think that the car material should generally be made of pure steel. In fact, it is not to make the car seats stretchable. Therefore, when many parts of the car body are made of aluminum alloy material, then for the aluminum alloy material How should the owners of the vehicle body carry out repairs and maintenance? Here we follow the experts to learn about the maintenance of the aluminum body.
Note one: Stretchability Due to the poor local stretchability of aluminum alloy plates, cracks are easily generated. Therefore, when the automobile body is manufactured, the manufacturer will replace the aluminum alloy plate with poor tensile strength into a high-strength aluminum alloy. This will be much better stretchability. Therefore, car owners must pay attention to ensure that the aluminum alloy does not deform when doing body maintenance. In order to avoid cracks.
Note two: When the size of the master on the maintenance of the car, the owners must pay attention to ensure that maintenance personnel have a good grasp of dimensional accuracy. Because it is difficult to control once rebound occurs. Therefore, it is recommended to use low-temperature heating to release the stress when repairing the aluminum body so as to make it stable without causing secondary deformation such as rebound.
Matters needing attention three: size control Because aluminum is softer than steel, in the maintenance of collision and a variety of dust adhesion and other reasons will make the surface of the parts produce scratches, scratches and other defects, so the mold cleaning, equipment cleaning, the environment The dust, air pollution and other aspects to take appropriate measures to ensure that the parts are in good condition.
