Effect of artificial aging system and parking time on properties of 7003 aluminum alloy for anti-collision beam
By heating 7003 aluminum alloy profiles at different temperatures and different times,the most suitable artificial aging sys-tem was finally obtained,that is,100℃×8 h+145℃×12 h.By comparing the mechanical properties test results of 7003 aluminum alloy profiles under different parking times,it can be known that after the extrusion of aluminum profiles is completed,it is necessary to turn the sequence for deep processing as soon as possible to reduce the processing difficulty and avoid tensile bending cracking,or-ange peel and other defects.
