7075-T651 Aerospace Grade High Strength Round Aluminum Bar for Aircraft Structural Parts

The 7075-T651 round aluminum bar is a high-strength zinc-alloyed product designed for demanding aerospace structural applications. With zinc as the primary alloying element, 7075 offers one of the highest strength-to-weight ratios among all aluminum alloys. Heat treated to T651 temper (solution heat treated, stress relieved by stretching, and artificially aged), this bar delivers exceptional mechanical properties suitable for critical load-bearing components.

• Zinc-based 7xxx series alloy with tensile strength ≥ 572 MPa
• T651 temper for optimized stress relief and dimensional stability
• Excellent fatigue resistance for cyclic loading applications
• Good machinability in the heat-treated condition
• Conforms to AMS 4045, ASTM B221, and GB/T 3191 standards

• Aircraft structural components and wing spars
• Landing gear parts and fuselage frames
• High-stress aerospace machined parts
• Defense and equipment components

All bars are coated with anti-rust oil and wrapped in waterproof kraft paper, then packed in fumigation-free plywood cases. Standard delivery within 5 working days for stock sizes, 15-25 days for custom production orders.
