Aluminum Round Bar 2024 T851 Cold Finish

Aluminum Round Bar 2024 T851 Cold Finish

Our 2024-T851 cold-finish aluminum round bar is a high-strength alloy aged to achieve superior mechanical stability. These bars are primarily used for gears and structural connectors in high-performance machinery and aircraft. The T851 temper offers higher resistance to stress-corrosion cracking and better hardness than the standard T351 version. This material is a favorite in the aerospace and racing industries where durability and weight reduction are essential.
