Cunoștințe comune despre aliajul de aluminiu -- produsele din aluminiu sunt utilizate pe scară largă în viața noastră. These products are made of different raw materials of aluminum products, inclusiv placa de aluminiu, bobina de aluminiu, folie de aluminiu, cerc de aluminiu, și bandă de aluminiu. În funcție de diferite produse și cerințe, există multe proceduri de procesare diferite. Aluminum alloy temper is divided into different categories.
Aluminum alloy temper state subdivision
1. H1 aluminum alloy temper: a single work hardening state, suitable for work hardening without additional heat treatment.
2. H2 aluminum alloy temper: a state of work hardening and incomplete annealing, suitable for incomplete annealing after the work hardening degree exceeds the requirements of the finished product, so that the strength of the product can be reduced to the specified index.
3. H3 aluminum alloy temper: a state of work hardening and stabilization; It is suitable for the products with low-temperature heat treatment after work hardening or stable mechanical properties due to the heating effect in the process of machining.
4. H4 aluminum alloy temper: a state of work hardening and painting; It is suitable for work hardening products with incomplete annealing due to paint treatment
5. H14 aluminum alloy temper: A work hardening to 1/2 hard H16 work hardening to 3/4 greu
6. H18 aluminum alloy temper: work hardening to 4/4 greu, which is fully hardened;
7. H19aluminum alloy temper: Ultra-work hardening state. The tensile strength of this material should be more than 10N/mm2 higher than that of the H18 state material;
8. H22 aluminum alloy temper: part annealed to 1/4 hard after work hardening;
9. H24 aluminum alloy temper: part annealed to 1/2 hard after work hardening;
10. H26 aluminum alloy temper: part annealed to 3/4 hard after work hardening;
11. H28 aluminum alloy temper: part annealed to 4/4 after work hardening;
12. H32 aluminum alloy temper: after work hardening, it is stabilized to 1/4 greu;
13. H34 aluminum alloy temper: after work hardening, it is stabilized to 1/2 greu;
14. H36 aluminum alloy temper: after work hardening, it is stabilized to 3/4 greu;
15. H38 aluminum alloy temper: after work hardening, it is stabilized to 4/4 greu;
16. H42 aluminum alloy temper: painted after work hardening, 1/4 greu;
17. H44 aluminum alloy temper: painted after hardening, 1/2 greu;
18. H46 aluminum alloy temper: painted after work hardening, 3/4 greu;
19. H48 aluminum alloy temper: painted after work hardening, 4/4 greu;
20. H111 aluminum alloy temper: Finally annealed, and then a small amount of work hardening (lighter than H11 hardening). This hardening is caused by operations such as stretching or straightening.
21. H112 is formed by hot work followed by a slight work hardening, or from a small amount of cold work followed by a slight work hardening to meet specific mechanical properties requirements.
22. H116 aluminum alloy temper: it is a special status code set for 5XXX series alloy with no less than 4% magnesium content. The aluminum-magnesium alloy material in this state not only reaches the set mechanical property level but also has good spalling and corrosion resistance
