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 — confirm with our team for seawater exposure.

T6 / T651 — peak strength for frames and fixtures. T7351 — better stress-corrosion resistance for outdoor or corrosive service. 7075 is not marine-grade.
Strongest aluminum hollow section for mass-critical structures.
Uniform properties across the section after stress-relief (T651).
Prefer mechanical fastening over fusion welding.
Aircraft structures, molds and dies, high-stress machine frames, fasteners and fittings, defense and sporting goods.
CNC machining and laser cutting are supported; anodizing with sealant is advised for corrosion service.
Every order ships with an MTC. SGS third-party test reports available on request. Linsy holds ISO 9001, ISO 14001 and ISO 45001.
