When the aluminum plate is used for exterior wall decoration, the hardness of the aluminum plate is particularly strict, which requires hardening treatment during the production process of the aluminum plate to improve the hardness of the aluminum plate and meet the performance requirements. So, what is the method of strengthening the hardening treatment of aluminum plate production? The following technicians will answer for you:

1. Processing reinforced aluminum plate:

Work strengthening, also known as cold work hardening, refers to the cold deformation of the aluminum plate below the recrystallization temperature, such as forging, calendering, drawing, stretching, etc. During the cold deformation process, the internal dislocation density of the aluminum plate increases, intertwined to form a honeycomb structure. This hinders dislocation motion. The greater the degree of deformation, the more severe the dislocation entanglement, the greater the deformation resistance and the higher the strength. The degree of strengthening after cold deformation varies with the degree of deformation, the deformation temperature and the properties of the material itself. When the same material is cold deformed at the same temperature, the greater the degree of deformation, the higher the strength and the lower the plasticity.

2. Solid solution strengthened aluminum plate:

Adding certain alloying elements to pure aluminum to form an infinite solid solution or a limited solid solution can not only obtain high strength, but also obtain excellent plasticity and good press workability. The most commonly used alloying elements for solid solution strengthening in general aluminum sheets are copper, magnesium, manganese, zinc, silicon, nickel and other elements. Generally, the alloying of aluminum plates forms a limited solid solution, such as Al-Cu, Al-Mg, Al-Zn, Al-Si, Al-Mn and other binary alloys all form a limited solid solution, and all have a large limit solubility. Larger solid solution strengthening effect.

The above is the introduction of the method of strengthening and hardening treatment of aluminum plate production. The hardness of the strengthened aluminum plate will be significantly improved, but its hardness cannot be continuously improved; when the upper limit of hardness is reached, no matter what method is used, it cannot be Continue to improve the hardness of the aluminum plate, and only choose a grade with a higher basic hardness.
