The 5 series alloy, namely aluminum-magnesium alloy, is currently the series with the best comprehensive performance among the 8 aluminum alloy series, and the number of grades is also the largest among the 8 series.

The main alloying elements of the 5 series aluminum plate are aluminum and magnesium, and the magnesium content is between 3% and 6%. The difference of the magnesium content determines the performance difference between the different grades of the 5 series aluminum plate.

Advantages of 5 series aluminum plate:

1. Good corrosion resistance. The 5 series aluminum plate is the most resistant to acid and alkali corrosion among the 8 aluminum plate series. This makes the 5 series aluminum plate suitable for the environment that most aluminum plates cannot adapt to, and greatly expands the application range of aluminum.
2. Good processability. The 5 series aluminum plate has high plasticity and good processing performance, and can be adapted to various processing methods such as bending, stamping, and stretching.
3. Good thermal conductivity. The 5 series aluminum plate has excellent thermal conductivity and is the best material for making equipment casings and radiators.
4. Strong resistance to pressure.
The hardness of the 5.5 series aluminum plate is higher among the eight aluminum plate series, and the strength can be improved by further processing. It is the main material for making high-end mobile phones and computer casings.

Disadvantages of 5 series aluminum plate:

Although there are many advantages, there are still many shortcomings of the 5 series aluminum plate that have not been solved. For example, the 5 series aluminum plate has poor wear resistance, high price, and poor cutting performance. These shortcomings also increase the use cost of the 5 series aluminum plate and limit the 5 Department of the development of aluminum plates.
