6XXX is a type of Al-Mg-Si alloy and 6061, 6063, 6351,6005 are the commonly used grades. Sometimes 6005 aluminum alloy can be used as a substitute material of 6063 and other profiles. The tensile strength and yield strength of 6005-T1d are equal to 6063-T5, but the elongation rate is twice that of the 6005-T1, which is more suitable for bent profiles and does not need to be artificially aged after arc bending like the 6063 profile, which reduces the process and saves the cost. The mechanical properties of 6005-T5 are higher than that of 6063-T6, with good air permeability, rainwater permeability, wind pressure deformation performance and in-plane deformation performance. 6005A aluminum alloy is a kind of medium strength deformation alloy developed on the basis of 6005. The strength of 6005A-T6 aluminum alloy is higher than that of extruded 6106-T6. They are characteristic by good extrusion performance and corrosion resistance, can be quenched on the extrusion machine, widely used in the subway, high-speed trains, all kinds of passenger trucks applications. We want to know the difference between them and we should tell the difference firstly.

2.General industrial aluminum and aluminum alloy extruded profiles 6005 and 6005A T5/T6
Through several tensile tests, it can be concluded that different delivery states and heat treatment states of 6005 and 6005A aluminum alloy profiles have different tensile strength, non-proportional extension strength and elongation after fracture. After the process of smelting -- ingot homogenization -- extrusion -- solid solution aging treatment, the tensile strength, yield strength and elongation of 6005A alloy were 62MPa, 62MPa and 3.5% higher than that of 6005 alloy under the conditions of 170℃/6h aging process. Under the conditions of maximum stress of 120Mpa, stress ratio of 0.1 and frequency of 20Hz, the axial fatigue cycles of both alloys exceeded 107 times.
