Technical Field

[0001] This utility model relates to the technical field of slotted reducing aluminum alloy tubes, specifically a high-performance slotted reducing aluminum alloy tube. Background Technology

[0002] Welded reducing aluminum alloy pipes are aluminum alloy pipes with different diameters at both ends, manufactured through welding.
