1 1/8" Aluminum Round Bar 2024-T351 Cold FinishPart #: mp-00065063
Sold & Shipped by Online Approved Seller
Select length:
Aluminum Round Bar 2024-T351 Cold Finish is a premier high-strength alloy engineered for the aerospace and defense sectors, prized for its exceptional fatigue resistance and high yield-to-weight ratio. The T351 temper indicates the material has been solution heat-treated and stress-relieved by stretching, a critical process that ensures the bar remains dimensionally stable and resists warping during intensive CNC machining. Because it is cold-finished, the bar possesses a smooth, polished surface and ultra-tight diameter tolerances, making it the ideal choice for precision components such as aircraft fasteners, gears, shafts, and hydraulic valve bodies. While its high copper content provides the necessary strength for structural tension, it does require anodizing or a protective coating for use in corrosive environments.
