Simple Cubic Structure (sc)Body-CenteredCubic (bcc)Face-Centered Cubic

Reduced Sphere representation

Note: Since each atom is shared by 8 unit cells, only 1/8 of each corner atom is inside each unit cell

Cubic lattices can be specified by a single lattice constant a.

  • Example of BCC metals: Fe, W, Mo, Nb, Ta, V, Cr
  • Examples of FCC metals: Cu, Al, Au, Ag, Pb, Ni, Pt Note fcc coordinates
  • Each atom on the faces is shared by two unit cells.
