Application

The purpose of the copper single crystal with a (110) orientation, measuring 15mm in diameter and 50mm in length, lies in its application as a high-purity, structurally uniform material for research and development in materials science and engineering. As a reddish-brown metal, copper is vital due to its excellent electrical and thermal conductivity, properties that are intrinsic to its face-centered cubic lattice structure with a lattice constant of 0.360775 nm. This single crystal form of copper is invaluable for understanding and manipulating the material's intrinsic properties, which are useful in various technological applications. Its uniform crystallographic orientation allows researchers and engineers to conduct precise experiments to explore copper's behavior under various conditions, contributing to advancements in electronics, catalysis, and other fields where copper's conductive, malleable, and ductile nature is advantageous. With a Poisson's ratio of 0.33 and electrical resistivity of 1.71 microhm-cm at 25°C, this form of copper is essential for experimental setups requiring predictable mechanical and electrical responses. The ability to conduct precise experiments using copper single crystals aids in the innovation of new materials and technologies, thereby reinforcing copper's longstanding importance in multiple industries.
