With nearly double the tensile strength and almost double the shear strength of 6061, our 7075 aluminum is laser cut or and is one of the best options available when high-strength and low-weight are important.
Like 6061 aluminum, 7075 aluminum was made for use in the aerospace industry, where it’s used extensively. It’s lightweight and durable, so it also lends itself to bike frames, rock climbing equipment, and other high stress environments.
7075 sacrifices some of 5052 aluminum’s workability, formability, and weldability for increased hardness, strength, and overall toughness.
