What Is 7075 Aluminum Square Tube?<\/h2>\n

7075 aluminum square tube delivers one of the highest strength-to-weight ratios among aluminum hollow sections, with zinc as the primary alloying element. Linsy supplies 7075 square tube in T6, T651 and T7351 tempers for aircraft structures, fixtures and high-load frames where dimensional stability and rigidity are critical. The T6\/T651 tempers give maximum strength; T7351 improves resistance to stress-corrosion cracking for structural use in corrosive environments. 7075 is not marine-grade \u2014 confirm with our team for seawater exposure.<\/p>\n
