How to make Aluminum extruded box from T3-T8 material


T3~T8 refers to the heat treatment process code for extruded profiles
The details are as follows:


After the solid - melt heat treatment T3 is processed by cold process, and then after natural aging to a basically stable state
It is suitable for cold processing, straightening and leveling to improve the strength of products after solid fusion heat treatment


T4
After heat treatment, the natural aging is stable
It is suitable for products that no longer undergo cold processing (short straightening, leveling, but not affecting the limit of mechanical properties) after solid fusion heat treatment

T5
It is cooled by high temperature forming process and then manually aged
It is suitable for products that are artificially aged after cooling by high temperature forming process without cold processing (straightening and leveling can be carried out without affecting the limit of mechanical properties)


T6
The state of artificial aging after solid - melt heat treatment
It is suitable for products that no longer undergo cold processing (straightening, leveling, but not affecting the limit of mechanical properties) after solid fusion heat treatment

T7 has
The state of over aging after heat treatment
It is applicable to products whose strength exceeds the peak point on the aging curve in order to obtain some important characteristics after the solid melt heat treatment


After the solid - melt heat treatment T8 is processed by cold processing and then artificial aging
Suitable for cold processing, straightening and leveling to enhance strength of products
