2124 seamless aluminum tube is a typical al alloy in al - Cu - Mg series tube.This alloy is produced in many countries and is used in the largest amount of hard aluminum roofing.The alloy is characterized by high strength, certain heat resistance and can be used as working parts up to 150°C.The strength of 2124 alloy is higher than that of 7075 alloy at temperatures above 125°C.In thermal state, annealing and new quenching state, the forming function is better, the strengthening effect of heat treatment is obvious, but the heat treatment process is strict.The corrosion resistance is poor, but it can be effectively protected by pure aluminum coating.It is easy to crack when welding, but special technology can be used for welding or riveting.Widely used in aircraft structure, rivets, truck wheel hub, propeller components and other structural parts.
2124 seamless aluminum tube ‘s physical properties



1. Low density
The density of aluminum and aluminum alloys is close to 2.7g/ m2, about 1/3 of that of iron or copper.
2. High intensity
High strength of aluminum and aluminum alloys.The matrix strength can be strengthened by a certain degree of cold working, and the departmental grade aluminum alloy can be strengthened by heat treatment.
3. Good electrical and thermal conductivity
Aluminium is second only to silver, copper and gold in its ability to conduct electricity and heat.
4. Good corrosion resistance
The surface of aluminum is easy to produce a layer of dense and firm aluminum oxide protective film, which can well protect the matrix from erosion.Forged aluminum alloy with good forging performance or deformed aluminum alloy with good machining plasticity can be obtained through artificial anodizing and coloring.
