A Here is a clear and technically accurate English translation of your text, using standard aluminum-alloy terminology commonly seen in GB / ASTM / EN contexts:
The temper (also referred to as processing condition) of 1050 aluminum alloy covers multiple types, mainly including annealed tempers and strain-hardened tempers, which can be classified as follows:
Annealed Temper (O Temper)
The material is fully annealed to eliminate residual stresses and soften the microstructure.
The typical annealing temperature range is 350–430 °C, followed by holding and furnace cooling.
This temper is suitable for applications requiring high ductility and excellent formability, such as deep drawing and complex forming operations.
Strain-Hardened Tempers (H Tempers)
Strength is enhanced through cold rolling, cold drawing, or other cold-working processes, resulting in a significant increase in tensile strength accompanied by a reduction in ductility.
Common sub-tempers include:
H12 / H14 / H16 / H18
Correspond to increasing degrees of cold deformation, with progressively higher strength and decreasing ductility.
H22 / H24 / H26 / H28
Suitable for moderate strength requirements, involving relatively large amounts of deformation.
H32 / H34 / H36 / H38
Represent high levels of cold work, providing the highest strength but low elongation.
Other Tempers
Some sources mention T-series heat-treated tempers (such as T351 and T651). However, 1050 aluminum alloy is primarily supplied in annealed and strain-hardened tempers, as heat-treatment strengthening is very limited for this alloy.
In practical applications, temper selection should be based on manufacturing processes and performance requirements.
For example, the O temper is commonly used for deep drawing and forming, while H tempers are selected for components requiring higher strength.
