3003 O Temper Welded Aluminum Tube – HVAC & Fluid Transfer Grade
Product Overview
3003 welded aluminum tube is a cost-effective piping solution manufactured by high-frequency welding of formed aluminum strips. It combines the corrosion resistance and lightweight of aluminum with the cost efficiency of welded construction. This O fully annealed grade provides maximum ductility for bending, expanding and forming operations. It is widely used in HVAC systems, fluid transfer, decorative structures and general industrial piping.
Why Choose CNB Welded Aluminum Tube?
Our welded aluminum tubes are produced on advanced high-frequency welding lines with strict control of weld quality, dimensional accuracy and surface finish. We perform full weld integrity testing and annealing to ensure consistent ductility and corrosion resistance. All tubes are deburred and cleaned before delivery, ready for immediate installation or fabrication.
