Application

The copper single crystal, with a diameter of 15mm and a length of 50mm in (100) orientation, serves as a fundamental material in both research and industrial applications. Due to its face-centered cubic lattice with a lattice constant of 0.360775 nm at 18°C, this product is critical for understanding the intrinsic properties of copper. Its use is essential in exploring the characteristics of copper, including its exceptional electrical and thermal conductivity, leading to applications in electronics and material science. Furthermore, the copper single crystal acts as a benchmark for studying the behavior of defects and dislocations within the metal's structure, providing insights into its mechanical properties. This makes it an invaluable tool for advancing technological innovations and material engineering.
