Aluminum 6061 is a lightweight, high-strength alloy with excellent machinability, weldability, and corrosion resistance. It is one of the most popular aluminum materials for 3D printing, especially suitable for parts requiring good surface quality and mechanical performance.
As a heat-treatable alloy, 6061 maintains stable workability after annealing and offers balanced strength and formability, making it ideal for industrial-grade applications.
