6005A 6005 T6 extruded structural aluminum angel bar is the most widely used rust-proof aluminum bar. 6005 alloy is widely used in extrusion of general-purpose. Any extruded profile and pipe with higher strength than 6063 alloy can be produced with this alloy. Like the 6063 alloy, they are pure Al-Mg-Si alloys. Except for Mg and Si, they contain no other alloying elements. Mg2Si is the only strengthening phase, and Mg and Si all form Mg2Si.
6005A 6005 T6 extruded structural aluminum angel bar has excellent squeezability and low quenching sensitivity. It can be quenched in-line by extrusion machine. Materials with wall thickness ≤ 3mm can be quenched by air. Another outstanding advantage of them is that they have a smooth surface and are easy to anodize and color.
6005A 6005 aluminum alloys extruded angle bar are mainly used for the manufacture of city rail passenger cars and railway passenger cars, especially for high-speed EMUs. The
6005A 6005 aluminum alloys extruded angle bar produced by Chalco has unique advantages. In the Al-Mg-Si heat treatable reinforced aluminum alloy, the 6005 alloy has no stress corrosion cracking phenomenon, and has the advantages of medium strength, excellent formability, corrosion resistance, and low density. 6005A can extrude a large wide flat thin-walled hollow profile with complex cross-section shape through large-scale extruder, which can realize on-line air cooling or water mist cold quenching on the extruder. The mechanical properties of
6005A 6005 T6 extruded structural aluminum angel bar are relatively high, and its air permeability, rainwater permeability, wind pressure deformation performance and in-plane deformation performance have reached the first level specified by national standards.
