Abstract

The invention discloses a time-efficient reinforced aluminium alloy extrusion, which belongs to the field of a metal material. The aluminium alloy extrusion comprises components, by weight percentage: 0.75-0.90 of Mg, 0.5-0.6 of Si, 0.10-0.14 of Cu, 0.20-0.25 of Mn, 0-0.1 of Ti, 0-0.1 of Cr, 0.1-0.3 of Fe, and 0.20-0.28 of Zn, and is balanced with Al. According to the invention, alloy components are optimized; steps of melting and casting, homogenization, extrusion, thermal treatment, and surface treatment in production technology are optimized; and mechanical properties and the surface film quality are effectively improved.

Description

technical field [0001] The invention relates to the field of metal materials, in particular to an aging-strengthened aluminum alloy profile. Background technique [0002] The advantages of sliding windows are simplicity, beauty, large window width, large glass block, wide field of view, high lighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, open in one plane, occupy less space, and install screen windows conveniently Wait. At present, sliding windows are the most widely used in doors and windows. Compared with other metal profiles, aluminum alloy profiles have the advantages of light weight, beautiful appearance and economy. At present, sliding windows are mainly made of aluminum alloy profiles. In the prior art, the performance of aging-strengthened aluminum alloy profiles is still not optimal, and continuous improvement is still needed. [0003] Therefore, how to obtain an excellent aluminum alloy profile by optimizing the...
