3A21 H112 aluminum tube Aluminum round 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. When using gas welding and argon arc welding, aluminum pipes tend to form intergranular cracks; After quenching and cold work hardening, the machinability of aluminum pipes is still good, but it is poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods or adding an aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as a mold material.

2A12 T4 aluminum tube is a kind of high-strength hard aluminum, which can be strengthened by heat treatment. It has medium plasticity under annealing, just quenching and hot state, and has good spot weldability. It has a tendency to form intergranular cracks when gas welding and argon arc welding are used; the alloy is quenched and The machinability is still good after cold work hardening, but it is not good in the annealed state. 2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be strengthened by heat treatment; 2A12 aluminum alloy has good weldability in spot welding, and has a tendency to form intergranular cracks when gas welding and argon arc welding are used; 2A12 aluminum alloy can be machinable after cold work hardening The performance is still good. The corrosion resistance is not high, and anodic oxidation treatment and painting methods are often used to improve the corrosion resistance.
