The seamless aluminum tube is made of pure aluminum or aluminum alloy by extrusion processing without weld. The seamless aluminum tube will be solid with each end without having any welding joint.
As the Aluminum seamless tube supplier, we provide alloy grade 3003 and 3103 seamless aluminum tube. Seamless aluminum tubes are produced by piercing extrusion, while conventional aluminum tubes are usually extruded by a combined die. Aluminum Alloy seamless tube is using short aluminum bars with high temperature, slow speed extrusion process, aging time and temperature are adjusted according to the thickness and diameter of the aluminum tubing.
