Abstract

The invention discloses a novel aluminum alloy tubular product. The novel aluminum alloy tubular product comprises, by weight percentage, 93.8-94.5% of aluminum, 3.8-4.3% of copper, 0.6-0.7% of manganese, 0.2-0.25% of cadmium, 0.3-0.4% of magnesium, 0.18-0.2% of iron, 0.12-0.15% of silicon and 0.14-0.16% of titanium. The novel aluminum alloy tubular product is reasonable in material matching and moderate in cost, and the manufactured aluminum alloy tubular product has high tensile strength, toughness and abrasion resistance and excellent fatigue life and is outstanding in economical efficiency and practicability.

Description

technical field [0001] The invention relates to an aluminum alloy pipe material, in particular to a novel aluminum alloy pipe material with excellent comprehensive performance and outstanding strength, and belongs to the technical field of aluminum alloy products. Background technique [0002] Aluminum alloy pipe is a kind of non-ferrous metal pipe. It is a metal tubular material that is hollow along its longitudinal full length by processing aluminum alloy profiles through extrusion, drawing and other processes. Aluminum alloy pipes can have one or more closed through holes, and the wall thickness and cross-section are uniform. According to the shape, it can be divided into: square tube, round tube, patterned tube, special-shaped tube, etc.; according to the extrusion method, it can be divided into: none Seam aluminum tubes and ordinary extruded tubes; according to precision, they can be divided into: ordinary aluminum tubes and precision aluminum tubes, among which precisi...
