ALUMINUM

Our aluminum hex bars combine high strength with excellent machinability, making them a go‑to choice for demanding projects. The most‑requested alloy is 6061‑T6 because it balances tensile strength, weldability, and heat‑treatability, but we also stock 2011‑T6 and 2024‑T3 for applications that need higher fatigue resistance or aerospace‑grade performance. All sizes are available in stocked lengths or cut to custom lengths with fast lead times, and every order is backed by SteelNow’s technical support.
