7A04 H16aluminum tube is a type of non-ferrous metal tube, which refers to a metal tube like material that is extruded and processed into a hollow longitudinal length using pure aluminum or aluminum alloy. The shape of the tube is circular.It is a high-strength hard aluminum that can undergo heat treatment and strengthening. It has moderate plasticity under annealing, hard quenching, and hot conditions, and good spot welding weldability.
7A04 H12 aluminum tube is an Al-Zn-Mg-Cu super-high-strength aluminum alloy, also known as super-duralumin , which is a relatively mature, long-term and widely-used alloy among super-duralumin. High strength, good heat treatment strengthening effect, medium plasticity in annealed and new quenched states; different from duralumin , the corrosion resistance in the artificial aging state is better than that in the natural aging state, and the natural aging process is slow, it needs to go through 3 The peak of age hardening can only be reached after one month, so 7A04 H12 aluminum tube is used in the state of quenching and artificial aging. The disadvantage is that the structure stability is not high, the low frequency fatigue strength is low, and there is a tendency of stress corrosion cracking. The alloy has good spot weldability , poor gas welding, good machinability after heat treatment, but poor machinability after annealing.
7A04 T5 aluminum tube is an Al-Zn-Mg-Cu super-high-strength aluminum alloy, also known as super-duralumin , which is a relatively mature, long-term and widely-used alloy among super-duralumin.

7A09 T5 aluminum tube belongs to Al-Zn-Mg-Cu super duralumin . This alloy has been used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry. It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150°C, and particularly good low-temperature strength; poor welding performance; tendency to stress corrosion cracking; needs to be coated with aluminum or other Protected processing use. Dual-stage aging can improve the alloy's ability to resist stress corrosion cracking. The plasticity in the annealed and just-quenched state is slightly lower than that of 2A12 in the same state. It is slightly better than 7A04. The static fatigue of the plate is sensitive to notches, and the stress corrosion performance is better than 7A04.
7A09 T3 aluminum tube is a type of non-ferrous metal tube, which refers to a metal tube like material that is extruded and processed into a hollow longitudinal length using pure aluminum or aluminum alloy. The shape of the tube is circular.It is a high-strength hard aluminum that can undergo heat treatment and strengthening. It has moderate plasticity under annealing, hard quenching, and hot conditions, and good spot welding weldability.
7075 T3 aluminum tube belongs to Al-Zn-Mg-Cu super duralumin . 7075 T3 aluminum tube is anultra-high-strength wrought aluminum alloy that has been used in the aircraft manufacturing industry in the late 1940s and is still widely used in the aviation industry It is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150°C, and particularly good low-temperature strength; poor welding performance; tendency to stress corrosion cracking; needs to be coated with aluminum or other Protected processing use. Dual-stage aging can improve the alloy's ability to resist stress corrosion cracking. Zinc is the main alloying element in 7075 T3 aluminum tube. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the heat treatment effect of the alloy far better than that of the aluminum-zinc binary alloy. Increasing the content of zinc and magnesium in the alloy will further increase the tensile strength, but its ability to resist stress corrosion and exfoliation corrosion will decrease accordingly. After heat treatment, it can achieve very high strength characteristics.
7075 T8 aluminum tube is a type of non-ferrous metal tube, which refers to a metal tube like material that is extruded and processed into a hollow longitudinal length using pure aluminum or aluminum alloy.
