O annealing state is suitable for the processed products with the lowest strength after complete annealing. H Work hardening state is suitable for products whose strength is improved by work hardening. After work hardening, the product may or may not undergo additional heat treatment to reduce its strength. The H code must be followed by two or three Arabic numerals W, which is an unstable state. It is only suitable for alloys that are naturally aged at room temperature after solution heat treatment. This status code only indicates that the product is in the natural aging stage T heat treatment state (different from F, O and H) and is suitable for heat treatment. With or without work hardening, T-code of products that reach a stable state must be followed by one or more Arabic numerals (GB/T 16475- 1996) old code, new code, old code, new code, M O CYS TX5 1, TX52RH1. Hx6MCSHXY subdivision state generation number and work hardening degree subdivision state generation number The work hardening degree HX 1 tensile strength limit is the middle value of O and HX2 states, HX2 tensile strength limit is the middle value of O and HX4 states, HX3 tensile strength limit is the middle value of HX2 and HX4 states, and HX4 tensile strength limit is the middle value of O and HX8 states. 5 tensile strength limit is the intermediate value of HX4 and HX6 states; The tensile strength limit of HX6 is the intermediate value of HX4 and HX8 states; The tensile strength limit of HX7 is the intermediate value of HX6 and HX8 states; HX8 hard state HX9 superhard state; And the minimum tensile strength limit exceeds the HX8 state by at least 10 MPa. Note: When the tensile strength limit of HX 1 ~ HX9 state determined according to the above table is not at the end of 0 or 5, the description of TX subdivision morphology and morphology to be used, and the description of the state to be used after T0 solution heat treatment, natural aging and cold working are applicable to the product T 1 with improved strength after cold working, which is cooled by high-temperature forming process and then naturally aged to a basically stable state. It is suitable for cooling by high-temperature forming process without cold working (straightening and leveling, but without affecting the limit of mechanical properties), cooling by high-temperature forming process, and naturally aging to a basically stable state after cold working, which is suitable for the product T3 cooled by high-temperature forming process, cold working after cold-working solution heat treatment, straightening and straightening to improve strength, and then naturally aging to a basically stable state, and is suitable for straightening after cold working or solution heat treatment. The product T4 leveled to improve the strength naturally aged to a basically stable state after solution heat treatment. It is suitable for the state that after solution heat treatment, the product T5, which is not cold-worked (can be straightened without affecting the mechanical property limit), is cooled by high-temperature forming process and then artificially aged. It is suitable for the state of cooling by high-temperature forming process without cold working (it can be straightened and straightened without affecting the mechanical performance limit). For the product T6 after solution heat treatment, the state of artificial aging is suitable for the product T7 after solution heat treatment, and no cold working is needed (straightening and straightening can be carried out without affecting the mechanical property limit). The over-aging state of the product T7 after solution heat treatment is suitable for the product T8 after solution heat treatment. In order to obtain some important characteristics, the strength of T8 product after solution heat treatment was cold worked during artificial aging. The artificial aging state is suitable for the artificial aging state after cold working, or straightening to improve the strength of T9 solution heat treatment, and then cold working. It is suitable for the state that T 10 which has been cold-worked to improve its strength is artificially aged after cold-working, and it is suitable for the products which have been cold-worked or straightened to improve its strength. Note: Some 6XXX series alloys can achieve the same effect of solution heat treatment, whether it is solution heat treatment in furnace or quenching from high temperature forming process to keep soluble components in solid solution. The T3, T4, T6, T7, T8 and T9 states of these alloys can be treated by either of the above two heat treatment methods. TXX and TXXX fine grain state generation number statement and applicable state generation number statement and applicable T42 are applicable to products that are naturally aged to a completely stable state after solution heat treatment in O or F state, and also to T62 products whose mechanical properties reach T42 state after heat treatment by the buyer in any state. The artificially aged products are also suitable for the products whose mechanical properties reach T62 state after heat treatment by the buyer. T73 is suitable for products whose mechanical properties and stress corrosion resistance have reached the specified indexes after solution heat treatment. The state definitions of T74 and T73 are the same. The tensile strength of this state is greater than that of T73 state, but the definition of T76 state is the same as that of T73 state. In this state, the tensile strength is higher than T73 and T74 respectively, and the stress corrosion cracking resistance is lower than T73 and T74 respectively, but its spalling corrosion resistance is still good. T72 is suitable for artificial aging treatment after O or F state solution heat treatment. The product T8 1 with mechanical properties and corrosion resistance reaching T7X state is suitable for solution heat treatment, and its cold deformation is improved by about 1%. Then T87, which is artificially aged, is suitable for solution heat treatment, and its strength is improved by cold working deformation of about 1%. Then, for the artificially aged products, use the extrusion tap _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ (2006-03-0716: 65438) to process aluminum alloy screw holes. Machining the screw hole on aluminum alloy workpiece with extrusion tap can prevent the screw hole from being damaged. Because air holes are easy to appear on the surface of aluminum alloy die castings below 1mm, it is easy to break threads by conventional processing techniques such as drilling and tapping, while the threaded holes processed by extrusion molding process have higher strength. Extrusion molding is a non-cutting process. Theoretically, the surface material reserved in the inner hole is equal to the volume of the formed thread per unit length. Based on this, it can be calculated that the size of the thread bottom hole processed by the extrusion tap is as follows: thread specification-bottom hole diameter m3-2.71mmmmm4-3.74mm5-4.64mm6-5.55mm (upper deviation +0.05mm, lower deviation-0.08mm) M8-7.45mmm10-.
