High-stability aluminum alloy section and manufacturing process thereof

Abstract

The invention discloses a high-stability aluminum alloy section and a manufacturing process thereof. The high-stability aluminum alloy section is composed of titanium coating layers, bearing surfaces, vertical beams, transverse beams, a center skeleton, a center hole and steel liners, wherein the center skeleton is square, one pair of the vertical beam and the transverse beam are in right-angle arrangement at each corner of the center skeleton, the bearing surfaces are arranged on the vertical beams and the transverse beams, each bearing surface forms a square with one pair of the vertical beam and the transverse beam, the corresponding four bearing surfaces on the center skeleton form a square, the steel liners are arranged in the connecting positions of the center skeleton and the vertical beams as well as the transverse beams, the titanium coating layers are arranged on the bearing surfaces, and the center hole is formed in the center of the center skeleton. According to the high-stability aluminum alloy section, a unique square structure of the center skeleton is adopted, so that the stability of the section is greatly improved.

Description

technical field [0001] The invention relates to the field of profiles, in particular to a high-stability aluminum alloy profile and a manufacturing process thereof. Background technique [0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry, and are widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, and decoration. And the chemical industry has been widely used. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. The wide application of aluminum alloy has promoted the development of aluminum alloy welding technology, and the development of welding technology has expanded the application field of aluminum alloy, so the welding technology of aluminum alloy is becoming one of the hot spots of ...

Problems solved by technology

The density of pure aluminum is small (ρ=2.7g / cm3), about 1 / 3 of that of iron, and its melting point is low (660°C). Aluminum has a face-centered cubic structure, so it has high plasticity, is easy to process, and can be made into various It is a kind of profile and plate with good corrosion resistance; but the strength of pure aluminum is very low, and the annealed state value is about 8kgf / mm2, so it is not suitable for structural materials
