        Introduction 7055 is the strongest of the common aluminum alloys, developed by Alcoa in 1991 for aircraft upper wing skins. It pushes zinc, magnesium, and copper higher than 7075 aluminum. The real decision is whether you need its peak strength enough to accept limited corrosion resistance and a structure that is not welded for primary […]<\/p>\n","protected":false},"author":1,"featured_media":8841,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"7055 Aluminum Alloy: Strength, Tempers and Aerospace Applications","_seopress_titles_desc":"Explore 7055 aluminum alloy - the highest-strength common grade (Zn-Mg-Cu).
