Overview

3105 aluminum is a 98% pure aluminum alloy with minor additions that make it stronger than 1100 or 3003 aluminum. 3105 has excellent formability, corrosion resistance, and weldability. 3105 is not a heat-treatable alloy. It is typcially used in applications that require higher strength than 1100 aluminum such as: residential siding, sign making, and mobile homes.
