Product Features Manufactured from premium AZ31B magnesium alloy with excellent machinability, lightweight performance and a high strength-to-weight ratio. Precision-cut to 100 × 100 mm (4" × 4") with a consistent 1mm (0.039") thickness for accurate machining, fabrication and engineering applications. Ideal for CNC machining, laser engraving, milling, drilling, engineering prototypes, model making, educational projects and custom fabrication. Bulk 5-pack provides multiple sheets for workshops, prototype development, engineering projects and repeated machining operations while offering greater value than purchasing individual sheets. AZ31B magnesium alloy combines low density, excellent machinability and reliable mechanical properties, making it an excellent material for lightweight structural and industrial applications. About AZ31B Magnesium Alloy AZ31B is one of the most widely used wrought magnesium alloys. It contains approximately 94–97% magnesium with aluminum and zinc as the primary alloying elements, providing an excellent balance of lightweight performance, mechanical strength and machinability. With a density of approximately 1.74 g/cm³, magnesium is one of the lightest structural metals available. It is widely used in aerospace, automotive, engineering, robotics, prototype development, scientific research and industrial manufacturing. Magnesium is also commonly used as a sacrificial anode material for cathodic protection systems because of its electrochemical properties. Its outstanding machinability makes it an excellent choice for CNC machining, precision components and custom fabrication projects. Notes Suitable for industrial, engineering, machining, educational and research applications. Slight surface oxidation is normal for magnesium alloy and does not affect machining or product performance. Actual product color may vary slightly due to monitor settings. Manual measurement may result in slight dimensional tolerances. Store in a cool, dry environment and avoid prolonged exposure to moisture.
