Seamless Nickel Alloy Pipe

According to the shape can be divided into: square tube, round tube, pattern tube, special shape tube; According to the extrusion method is divided into: Seamless Aluminum Tube, ordinary extrusion tube; According to the accuracy, it is divided into ordinary Aluminum Tube and precision aluminum tube. The precision aluminum tube generally needs to be reprocessed after extrusion, such as cold drawing and rolling. According to thickness, it is divided into ordinary aluminum tube and thin-walled aluminum tube.Seamless aluminum tube belongs to high strength duralumin, which can be strengthened by heat treatment. In quenching and hardening state, it has medium plasticity, good spot welding, and tends to form intergranular cracks with gas welding.Aluminum tube is a kind of high strength duralumin, which can be strengthened by heat treatment. It has medium plasticity in annealing, hardening and hot state, and good weldability in spot welding. When using gas welding and argon arc welding, aluminum tube has the tendency to form intergranular cracks; The machinability of aluminum tube is good after quenching and cold hardening, but bad when annealed.
