FCC (Face-Centered Cubic)

The Face-Centered Cubic (FCC) is a common arrangement of atoms in certain metals, like aluminum, copper, and gold. Imagine a cube where atoms are placed at each corner and at the centers of each face. This pattern creates a highly efficient, dense packing of atoms, allowing the material to be strong and ductile. The FCC structure is known for its symmetry and ability to deform under stress without breaking, making it important in materials science for understanding and developing strong, flexible metals.
