2014 aluminum is used in applications requiring high strength and hardness including high temperature. Aircraft heavy duty, forgings, plate and extruded materials, wheels and structural elements, multi-stage rocket stage fuel tanks and spacecraft parts, truck frames and suspension system parts.
2017 aluminum is a 2XXX series alloy that has obtained industrial applications. The current application range is narrow, mainly for rivets, general mechanical parts, structural and transportation structural parts, propellers and accessories
2024 aluminum is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. Many countries produce this alloy, which is used in a large amount of duralumin. The characteristics of the alloy are: high strength, certain heat resistance, and can be used as working parts below 150 °C. Widely used in aircraft structures, rivets, truck hubs, propeller components and various other structural parts.
2A02 aluminum Axial compressor blades of turbojet engines with operating temperature of 200~300 degrees Celsius
2A06 aluminum Aircraft structures with a working temperature of 150~250 degrees Celsius and structural rivets with a working temperature of 125~250 degrees Celsius
La 2124 aluminum aluminum plate is the American grade, and the Chinese grade is 2A12. The alloying element of 2124 is copper, which is called duralumin, which has high strength and good cutting performance, but general corrosion resistance. It is widely used in aircraft structures (skin, skeleton, rib beam, bulkhead, etc.), rivets, missile components, truck hubs, propeller components and other various structural parts. It is Al-Cu-Mg system.
2A14 aluminum is used for occasions requiring high strength and hardness (including high temperature). Aircraft heavy duty, forgings, plate and extruded materials, wheels and structural elements, multi-stage rocket primary fuel tanks and spacecraft parts, truck frames and suspension system parts.
2A17 aluminum is usually used in rivets, general mechanical parts, aircraft, navires, transportation, building structural parts, transportation structural parts, propeller components and accessories.
2A11 aluminum This is a kind of hard aluminum that has been used for a long time. It is generally called standard hard aluminum. It has medium strength, good plasticity in annealed, just quenched and hot states, and can be strengthened by heat treatment. It is used in quenched and natural aging states, spot welding Weldability is good.
2A10 aluminum is an alloy for rivets. High shear strength, sufficient plasticity required for riveting rivets in annealed, just quenched, aged and hot states; riveted with quenched and aged rivets, the riveting process is not limited by the time after heat treatment. The weldability of aluminum plate 2A10 is the same as that of 2A11, and the corrosion stability of rivets is the same as that of 2A01 and 2A11. When heated above 100°C.
