Aluminum Alloy Basic State Code

The letter H is usually followed by two digits: the first digit indicates the method of work hardening. The first number after the H is: 1, 2, 3, 4

That is, H1* H1* means simple work hardening

The second number indicates the degree of hardening achieved by the material.

The second number after the H is: 1, 2, 3, 4, 5, 6, 7, 8, 9

H1 Hardness between 0 and 2 H2 1/4 Hard H3 Hardness between 2 and 4 H4 1/2 Hard H5 Hardness between 4 and 6 H6 3 /4 Hard H7 Hardness between 6 and 8 H8 Full Hard H9 Super Hard (H followed by three numbers is not much, only a few. H111 indicates that a moderate amount of work hardening has been carried out after final annealing .H112 indicates products suitable for hot forming. H116 indicates 5 products made of alloys with magnesium content ≥ 4.0% **.)

The state code behind our common heat-treated aluminum alloys is generally the letter T plus one or more Arabic numerals to indicate the subdivision state of T. Add 0-10 Arabic numerals after T to indicate the subdivision state (called TX state). The number after the T indicates the heat treatment procedure of the product. After T0 solution heat treatment, naturally aged, then cold worked condition. Suitable for products with increased strength through cold working.

T1 is cooled by a high temperature forming process, and then naturally aged to a basically stable state. It is suitable for products that are not cold processed after cooling by high temperature forming process (straightening and leveling can be carried out, but the mechanical performance limit is not affected). T2 is cooled by a high temperature forming process, and then naturally aged to a basically stable state after cold working. It is suitable for products that have been cold worked, straightened, straightened, and cooled by a high temperature forming process to increase their strength. T3 cold working after solution heat treatment, and then naturally aged to a substantially stable state. It is suitable for products that are cold worked, straightened and straightened after solution heat treatment to improve strength. After T4 solution heat treatment, it is naturally aged to a basically stable state. It is suitable for products that are not subjected to cold working after solution heat treatment (straightening and leveling can be carried out, but the mechanical properties are not affected), and then natural aging treatment is carried out. T5 The state of artificial aging after cooling by high temperature forming process. It is suitable for products that have not been cold-worked (can be straightened and leveled, but does not affect the limit of mechanical properties). Artificial aging state after T6 solution heat treatment. It is suitable for products that are not subjected to cold working after solution heat treatment (straightening and leveling can be carried out, but the mechanical properties are not affected), and then artificial aging treatment is carried out.

After the T10 is cooled by the high temperature forming process, it is cold worked and then artificially aged. Suitable for cold worked, or straightened or leveled products to increase the strength of the product. T status and TXXX status (except stress relief status) Add one more Arabic numeral after the TX status code (called TXX status), or add two Arabic numerals (called TXXX status), indicating that the product characteristics have changed significantly (such as mechanical properties, corrosion resistance, etc.) the processing state of the specific process.

T42 is suitable for products whose natural aging reaches a sufficiently stable state after solid solution heat treatment in O or F state, and is also suitable for products whose mechanical properties reach T42 state after heat treatment of processed products in any state by the buyer.
