With the urgent requirement of automobile weight reduction, the automobile body is made of larger aluminum alloy and it has become a trend to replace steel with aluminum. The main aluminum alloy materials used for the car body are 2 series aluminum-copper-magnesium alloy, 5 series aluminum alloy, 6 series aluminum-magnesium-silicon alloy, and 7 series aluminum-zinc-magnesium-copper alloy.
Most of them are heat-treated strengthened aluminum alloys. Series 5 aluminum alloys have good corrosion resistance and are mostly used in the bodies of refrigerated trucks and chemical storage trucks, as well as other large vehicles in combination with steel plates as linings.
There are many types of aluminum alloys used in automobiles.
Therefore, when considering the recycling of automotive aluminum alloys, it is important to distinguish the alloy series of various aluminum alloys and process them according to the alloy series as much as possible. This can reduce the difficulty of processing recycled metals and improve product quality.
