Common problems in aluminum profile processing:

        A. Alkali, can not touch the skin for a long time;

        B. It is not suitable to use lacquer finish panel. Polished or protected surfaces of aluminium profiles and finished parts of cars;

        C. Clean old facilities or rusted surface should pay attention to check whether there is leakage;

        Aluminum profile processing manufacturers analyze physical properties.

        After the cold deformation of industrial aluminum profiles, because of the destruction of intragrystalline and intergranular, lattice distortion and the occurrence of the second type of internal stress, so that the plasticity index value plummeted, in the limit case is likely to be close to the complete ductility; On the other hand, because of lattice distortion, texture increase, crystal length optimization and the occurrence of sub-structure, and so on, the compressive strength index value is greatly increased, that is, cold hardening occurs. Relative density. After cold deformation, the relative density of aluminum profile is reduced due to the defects of microscope crack or macro economic industrial aluminum profile crack, crack and so on.
