Abstract

The invention belongs to the field of extrusion of aluminum alloy profiles and relates to a series 6 aluminum alloy profile, comprising, by weight, 0.6-1.2% of Si, 0.5-0.7% of Mg, 0.1-0.4% of Mn, 0.1-0.3% of Cr, 0.1-0.35% of Zr, 0.1-0.24% of V, 0.1-1% of Fe, 0.05-0.3% of Ti, 0.03-2.5% of Zn, < / =0.05% of Cu and the balance of Al; a traditional common aging process is modified into a four-stage low-temperature short-term pre-aging process for a preparation method of the invention to inhibit standing effect of the aluminum alloy profile, the prepared aluminum alloy profile can still retain its mechanical properties after long-term standing, and final properties of the aluminum alloy profile are well improved.

Description

technical field [0001] The invention belongs to the field of aluminum alloy profile production, and relates to a 6-series aluminum alloy profile and a preparation method thereof. Background technique [0002] Aluminum alloy has the advantages of low density, good electrical conductivity, high thermal conductivity, and corrosion resistance. Therefore, using aluminum alloy as a structural material can greatly reduce product weight and increase structural stability, and is widely used in production. In particular, the 6-series aluminum alloy, which is used as a material for permanent magnet trains, can not only reduce the weight of the car body, but also significantly reduce the energy consumption of the car while meeting the structural strength requirements. It can be seen that aluminum alloy will replace steel material and become the main material of future train body. As one of the main load-bearing materials of rail vehicles, rail vehicle suspension arm profiles are subjec...
