6005 alloy is widely used in extrusion of general-purpose aluminum. It is required to produce the alloy with the strength of the material larger than that of the 6063 alloy. Like the 6063 alloy,
6005 extruded aluminum profile are all A-mg-si alloys, except Mg and Outside Si, it contains no other chemical elements, and Mg2Si is its only strengthening phase. Mg and Si form Mg2Si with excellent squeezability and low quenching sensitivity. It can be quenched in-line by extrusion machine. Materials with wall thickness ≤ 3mm can be air-quenched and quenched. Another outstanding advantage of them is that they have a smooth surface and are easy to anodize and color..
The 6005 alloy has good squeezable properties. The aluminum profile manufacturer should have a lower extrusion speed than the 6063 alloy. The maximum compression speed should not exceed 45 m/min. The
6005 extruded aluminum profile have good forming properties, good surface treatment performance and high corrosion resistance. They can be applied under industrial atmosphere and marine atmosphere without stress corrosion and exfoliation corrosion sensitivity.
6005 extruded aluminum profile is currently widely used in extrusion ladders, wheelchairs, TV antennas, gantry products and other profiles and pipes, but it should be noted that 6005 alloy can not be used to withstand the impact load structure.
