Aluminum Round Bar 2024 T351/T4 Cold Finish

Aluminum Round Bar 2024 T351/T4 Cold Finish

The 2024-T351 cold-finish aluminum round bar is an elite structural material known for high strength and fatigue resistance. This material is widely used for manufacturing aircraft bolts and precision-machined parts for the aerospace industry. The cold-finish process provides excellent surface quality and tight diameter tolerances for use in automatic screw machines. The T351 temper indicates the material is stress-relieved by stretching, which prevents warping during machining. Onlinemetals.com stocks 2024-T351 round bars in a wide range of diameters to suit your aerospace manufacturing needs.
