Seeking aluminum grade and temper expertise for recommendations to eliminate part warpage. Grade 3003 has been utilized historically for sheet metal enclosures on some of our equipment products. Those were liquid spray painted for finished surfaces. We would like to change to a powder coat process that utilizes a 10 minute @ 400 F thermal step. Some (not all) parts are warping slightly after powder coat. Our parts are made from 48" wide roll stock with nominal sheet thickness of 0.063". We have heard that 5052 is common for sheet metal panels and enclosures. Can anyone recommend aluminum grades and tempers that will reduce/eliminate the post-coating warpage?
