Characteristics of 6-200mm aluminum tube:

Aluminum tube is a high-strength hard aluminum that can be strengthened by heat treatment. The plasticity of aluminum tube is moderate in annealing, hard quenching, and hot state. The spot welding weldability of aluminum tube is good, and there is a tendency to form intergranular cracks when using gas welding and argon arc welding; The machinability of aluminum pipes is still good after quenching and cold work hardening, but it is poor when in the annealed state. Aluminum pipes have low corrosion resistance, and they are often treated with anodizing and painting methods or coated with aluminum to improve their corrosion resistance. Aluminum tubes can also be used as mold materials.
