@@@ series aluminum alloys are aluminum alloys with main alloying elements. They include alloys, alloys and alloys, etc. These alloys are all aluminum alloys that can be strengthened by heat treatment. The alloy is characterized by high strength, good heat resistance and processability, but its corrosion resistance is not as good as that of most other aluminum alloys. Under certain conditions, intergranular corrosion will occur. Therefore, the plate often needs to be coated with a layer of pure aluminum. Or a layer of aluminum alloy with electrochemical protection for the core plate to improve its corrosion resistance. Among them, the alloy has an extremely complex chemical composition and phase composition. It has high strength at high temperatures and has good process performance. It is mainly used for forging heat-resistant parts that work in ~. Although the room temperature strength of the alloy is lower than that of the alloy , but its strength is higher than the two at ~ or higher temperatures, and the alloy has good process performance and is easy to weld. It is mainly used in heat-resistant and weldable structural parts and forgings. @@@ series aluminum alloys are widely used in aviation and aerospace fields.
Alcoa Corporation of America successfully developed an aluminum alloy in 2016, which is mainly used to produce thick and thin plates for aircraft structural parts. , is mainly used to manufacture high-temperature structural parts and high-strength welding parts of aircraft. The aluminum alloy was successfully developed in 2016. It is mainly used to produce state-of-the-art extruded parts. It has been used to manufacture structural parts of Boeing and other aircraft. The successfully developed aluminum alloy is used to manufacture The thick plates and thin plates in the state have also been used to manufacture structural parts of Boeing and other aircraft. In recent years, aluminum alloys with better comprehensive properties have been developed.

Characteristics and scope of application
Aluminum alloys are both hard aluminum alloys and wrought aluminum alloys from the composition point of view. Compared with aluminum alloys, due to the higher copper content, they have higher strength and better thermal strength, but their plasticity in the hot state is not as good as aluminum alloys. It has good machinability, good performance in contact welding, spot welding and seam welding. Poor arc welding and gas welding performance can be strengthened by heat treatment. It has extrusion effect and low corrosion resistance. It has a tendency of inter-inspection corrosion during artificial aging.

Aluminum
It is a typical hard aluminum alloy in the aluminum, copper and magnesium series. Its composition is relatively reasonable and its overall performance is good. . This alloy is produced in many countries and is the most widely used among duralumin. This alloy is characterized by high strength and certain heat resistance, and can be used as the following working parts. The temperature is higher than that of the alloy, and the strength of the alloy is higher than that of the alloy. The formability is relatively good in the hot state, annealed and newly quenched states, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum. It is easy to crack during welding, but it can be welded or riveted using special technology. Widely used in aircraft structures, rivets, truck wheels, propeller components and other structural parts.
Material Usage
Aluminum plates are usually used in rivets, general mechanical parts, aircraft, ships, transportation, building structural parts, transportation structural parts, propeller components and accessories, etc.

Heat treatment process
Comparison of formability in the state, annealed and newly quenched states Good, the heat treatment strengthening effect is significant, but the heat treatment process requires strict requirements. The corrosion resistance is poor, but it can be effectively protected by pure aluminum coating. Cracks are prone to occur during welding, but special processes can be used to weld or rivet.
