Aluminum 6061
CNC Machining
Overview
6061 (T6) aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. 6061 aluminum material belongs to heat-treatable strengthening alloys, with good formability, weldability, and machinability. It has medium strength and can maintain good operability after annealing. The main alloying elements are magnesium and silicon, which form the Mg2Si phase.
