Abstract

The invention provides a processing technology of an aluminum alloy profile. The processing technology at least comprises the following steps that an aluminum alloy ingot, an extrusion die and an extrusion barrel are respectively heated so that the temperatures of the aluminum alloy ingot, the extrusion die and the extrusion barrel are 480-500 DEG C, 435-445 DEG C and 410-420 DEG C correspondingly; the heated aluminum alloy ingot is placed in the heated extrusion barrel for extrusion treatment, and the heated aluminum alloy ingot is extruded from a die hole of the heated extrusion die to obtain a first extrusion profile; the first extruded profile is sequentially subjected to on-line quenching treatment, sawing treatment and tension straightening treatment, and finally, artificial aging treatment is carried out under the aging conditions of 195-205 DEG C for 5-8h to obtain the aluminum alloy profile. The aluminum alloy profile obtained by the technology is small in grain size, micro gap amount is reduced and micro gap size is reduced, the conductivity reaches 56% or more, and the comprehensive mechanical properties are good.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing and manufacturing, and in particular relates to an aluminum alloy profile processing technology and the aluminum alloy profile. Background technique [0002] The material of traditional conductive aluminum profile products is 6101B, which is a heat-treatable alloy with excellent electrical conductivity and medium strength. In the process of use, the hardness of this type of product must be controlled within a medium strength range, the elongation must meet the standard requirements, and the electrical conductivity must reach more than 55%, which is difficult to produce. And with the upgrading requirements of product quality, some merchants require that the tensile strength of this type of product is ≧215MPa, the yield strength is ≧168MPa, the elongation is ≧6%, and the conductivity IACS is ≧56%. [0003] Some manufacturers use over-aging methods to improve conductivity, but the ...
