Aluminum tube is a kind of high-strength duralumin, which can be strengthened by heat treatment. It has moderate plasticity in reverse, just quenched and hot conditions. It has good spot welding and weldability. The aluminum tube will form intergranular cracks when gas welding and argon arc welding are used. ; The machinability of the aluminum tube after quenching and cold work hardening is good, but it is not good in the reverse state. The series connection is not high, and aluminum profile anodizing is often used to improve corrosion resistance.
The
anodized extruded aluminum tube refers to the process in which aluminum and its alloys form an oxide film on the aluminum tube (anode) due to the action of the applied current under the corresponding electrolyte and specific process conditions. If anodizing is not specified, it usually refers to sulfuric acid anodizing. In order to overcome the defects of aluminum tube surface hardness, wear resistance and other aspects, expand the scope of application, and extend the service life, the surface treatment technology of
anodized extruded aluminum tube has become an indispensable part of the use of aluminum tube, and anodizing technology is currently used The widest and most successful.
