1kg Niobium Cube

Measuring almost 2.0 inches (49mm cubed) and weighing 1kg, this massive block of solid niobium is the ultimate physical display of element 41. Includes a bespoke Atomic Cubes box and protective Atomic Cubes drawstring bag. Atomic Properties of Niobium Superconductive Metal: Conducts current without resistance below 9.2 Kelvin. Extreme Thermal Limit: Boasts an extraordinarily high melting point of 2477°C (4491°F). Uncommon Solid State: Almost all global production goes into steel alloys, making a pure block rare. Distinct Hue: Cooler and lighter in tone than steel, carrying a characteristic faint blue cast. Cold Ductility: Possesses high ductility for cold working despite its massive heat resistance.
