Some of the old platter drives used glass. Close enough 😂
Copper has a face-centered cubic (fcc) crystal structure, also known as A1 in the Bravais lattice classification. This structure is characterized by atoms located at each corner of a cube and at the centers of all cube faces.
Space Group: Fm-3m (No. 225)
Lattice Constant: Approximately 361.5 pm at 20 °C
Atoms per Unit Cell: 4
Coordination Number: 12 (each copper atom is surrounded by 12 nearest neighbors)
Atomic Packing: The fcc structure allows for high atomic density, contributing to copper’s high electrical and thermal conductivity.
