Comprehensive collection of metal cubes featuring tungsten, titanium, bismuth, carbon, aluminum, iron, magnesium, copper, zinc, chromium, nickel, tin, antimony, zirconium, molybdenum and more. Each cube is produced to purity standards, with purity levels ranging from 99.5 percent to 99.99 percent across different elements. Key features and benefits Precision manufacturing: Sharp corners and smooth faces produced with tight dimensional control, industry tolerance of (+/0.1) mm, for consistent size and appearance. Clear identification: Laser engraving on each aluminum cube shows atomic number, chemical symbol, element name, density, atomic mass and stated purity to support learning and cataloging. Standard size: Cubes measure 25.4 x 25.4 x 25.4 mm (1 inch) for a uniform, easy to handle reference set. Protective packaging: Individual cubes are vacuum packed to preserve natural appearance and reduce surface oxidation. Organized storage: A small 1 inch acrylic storage box is provided to keep elements separated, prevent surface scratches and simplify display. Material note: Metal sample cubes include density aluminum element cubes with purity up to 99.99 percent. These samples are suitable for handson educational use, element collections and display. How this product solves common needs Accurate reference pieces for classrooms and labs needing physical examples of elemental metals. Durable, labeled specimens for collectors who require consistent sizing and clear identification. Readytouse samples for demonstrations of density, weight comparison and basic material properties. Typical use scenarios Classroom demonstration: Teachers can use the engraved cubes to illustrate periodic table properties, atomic mass and density in middle school and school science lessons. Collector display: Organized, vacuum packed cubes arranged in the included acrylic box provide a neat exhibit for a collection or desktop display. Lab or workshop reference: Use the uniform 1 inch cubes for quick visual and tactile comparison of metals during material selection, hobby experiments or basic density tests.
