diffrence between 3003 alloy, and 7075 t6??

[whitrzac]

after waiting a week on some 7075 t6, WI metals said that they couldn't get it in, so there sending some 3003(all the info I was given) in the same size/thickness. they say that its close to the 7075, but IDK if its enough...


its going to be a chassis/motor plate/etc for my jato and e-maxx

if not, does someone have a 14"x 5"x1/8(or 3mm)+extras for the motor mount, sheet of 6061/7075 they could sell me??
