Magnesium Alloy Profiles

Magnesium alloy extrusion profiles offer the most favorable strength-to-weight ratio of any structural metal, with a density approximately 35% lower than aluminum and 75% lower than steel. For applications where minimum weight is the overriding design requirement—and where the limitations of magnesium are understood and managed—these profiles deliver structural performance that no other metallic extrusion material can match.

Our magnesium extrusion solutions are based primarily on AZ31 and ZA61A alloys, with select products incorporating rare earth (RE) element additions to enhance elevated-temperature strength, creep resistance, and corrosion performance. AZ31 is the most widely used wrought magnesium alloy, offering a practical balance of formability, weldability, and mechanical properties. ZA61A provides higher strength and is preferred where structural loads are more demanding.

Key application-driven properties include excellent vibration and acoustic damping—approximately five times greater than aluminum—making magnesium profiles effective in reducing noise and vibration transmission in sensitive assemblies. Electromagnetic shielding effectiveness is also superior to aluminum in many frequency ranges, relevant for electronic enclosure applications. These characteristics have made magnesium alloy profiles a growing choice in 3C electronics, lightweight transportation structures, and medical device frameworks.

Corrosion protection requires careful attention; appropriate surface treatment (micro-arc oxidation, chemical conversion coating, or painting) is specified based on the service environment. We provide full engineering support for surface treatment selection, alloy qualification, and dimensional tolerance definition for magnesium extrusion programs.
