aluminium extrusion profile for automotive

6005 aluminum extrusion for automotive door
6005 Aluminum extrusion for automotive door
The automotive door aluminum alloy profile is 6005A or 6005 alloy extrusion, which belongs to 190Al-Mg-Si-Mn-Cr alloy, heat treatment can be strengthened, the main strengthening phase is Mg2Si, increase Mg and Si content can improve the strength, but the content is too large, the formation of Mg2Si particles also, quench sensitivity increased, to improve the speed and strength of rising online quenching., and extrusion properties of bending performance profile variation, the surface profile appeared more extrusion stripes. Therefore, the use of 6005 alloy, no Mn and Cr, and 6005A alloy (Mn+Cr) content of 0.12%--0.50%.
