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 aluminum surface and finished product surface of car;

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

Aluminum profile processing manufacturers analyze physical properties.

After cold deformation of industrial aluminum profiles, because of the intragrystalline and intercrystalline destruction, lattice constant caused 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, due to lattice constant distortion, texture increase, grain length optimization and substructure, and so on, the compressive strength index value is greatly increased, that is, cold hardening occurs.

Physical and chemical properties of aluminum alloy profiles

1) 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.

2) Resistor. The destruction of intergranular components leads to direct grain contact, scientific grain location, intergranular and intragranular cracking, etc., which have significant harm to the transformation of resistance value.
