Product Features Manufactured from premium AZ31B magnesium alloy with excellent machinability, lightweight performance, high strength-to-weight ratio and reliable mechanical properties. Precision-cut to 200 × 200 mm (8" × 8") with a consistent 1mm (0.039") thickness, providing a lightweight and versatile sheet suitable for precision fabrication and engineering use. Ideal for CNC machining, milling, drilling, engraving, laser cutting, tooling fixtures, robotics, aerospace prototyping, automotive components and industrial manufacturing applications. The 1mm thickness offers excellent flexibility and formability while still maintaining sufficient strength for lightweight structural and prototype applications. AZ31B magnesium alloy provides low density, good vibration damping and excellent machinability, making it suitable for precision engineering and custom fabrication projects. About AZ31B Magnesium Alloy AZ31B is one of the most widely used wrought magnesium alloys, containing approximately 94–97% magnesium with aluminum and zinc as the primary alloying elements. It provides a strong balance of lightweight performance, mechanical strength and corrosion resistance under normal conditions. With a density of approximately 1.74 g/cm³, magnesium is significantly lighter than aluminum and steel, making it ideal for aerospace, automotive, robotics, CNC machining, prototype development and precision engineering applications. AZ31B also offers excellent machinability and vibration damping properties, making it widely used in precision components, tooling fixtures and custom fabricated parts. Magnesium is additionally used as a sacrificial anode material due to its electrochemical characteristics. Notes Suitable for industrial, engineering, machining, educational and research applications. Slight surface oxidation is a natural characteristic of magnesium alloy and does not affect machining performance or material quality. Always wear appropriate eye, respiratory and personal protective equipment when machining magnesium materials. Actual product color may vary slightly due to monitor settings. Manual measurement may result in slight dimensional tolerances. Store in a dry environment and avoid prolonged exposure to moisture.
