• Application: The copper single crystal with a 15mm diameter and 50mm length, oriented in the (111) configuration, serves multiple purposes due to its unique properties and structure. This single crystal of copper, characterized by its reddish-brown color and face-centered cubic lattice with a lattice constant of 0.360775 nm at 18°C, exemplifies the exceptional conductivity and malleability of copper as a metal. With a density of 8.92 g/cm³ and Mohs hardness of 2.5 to 3.0, it embodies the essential traits that make copper indispensable in various applications. Its Brinell hardness of 43 (when annealed) makes it suitable for precision uses, including electrical and thermal conductivity applications, due to its low electrical resistivity of 1.71 microhm-cm at 25°C. Copper's historic significance and modern-day applications-ranging from coinage and electronics to construction and chemical processing-highlight its versatility and critical role. In particular, the copper single crystal's orientation and purity are crucial in scientific research, potentially offering enhanced mechanical and physical properties that are invaluable for advanced materials science studies, semiconductor manufacturing, and metrology. This product, due to its orderly atomic structure and consistent properties, is essential for experiments and applications that require high levels of accuracy and reproducibility.
