Magnesium Cube 12.7mm (0.5 inch), 99.9% Pure Mg Metal Element Cube, Low-Density Lightweight Cube for STEM Education, Science Display & Collection

Discover the lightweight characteristics of magnesium with this precision-machined Magnesium Cube 12.7mm / 0.5 inch. Made from 99.9% pure magnesium, this Mg element cube is designed for STEM education, classroom demonstrations, density comparison, laboratory display, periodic table collections, and material observation. Magnesium is known for its low density of approximately 1.74 g/cm³, making it one of the lightest commonly used structural metals. With a compact size of 12.7 × 12.7 × 12.7mm, this cube has a theoretical weight of about 3.56g, making it ideal for comparing weight and density differences with heavier element cubes such as iron, zinc, copper, titanium, and tungsten. The cube is precision-machined into a clean geometric shape and is suitable for science classrooms, desktop display, element collections, density experiments, and hands-on material learning. Its small 0.5 inch size makes it easy to store, handle, and compare with other metal samples. Please note that this magnesium cube is made with right-angle edges and is not chamfered. Handle carefully during use and display. Magnesium should be kept away from open flames, high heat, grinding, cutting, sparks, or impact. This product is intended for educational, display, and collection purposes only.
