Standards & Properties: Metallurgy of Copper-Base Alloys All of the three qualities above are directly related to the structure and behavior of copper's structure on an atomic scale. Solid copper can be described as the arrangement of copper atoms in a face-centered-cubic (fcc) configuration. A copper atom is found at each corner and in the center of each face of a cube as depicted in Figure 1. This is the unit cell which is repeated in three dimensional space to make up the crystal structure of the metal. The atoms are held in place in the structure by the energy of the atomic attractions between them. It is this particular face-centered cubic arrangement of the atoms that gives copper its high ductility and toughness. All metals deform by means of a mechanism called slip. When slip occurs, a force on the metal causes the atoms to slide past one another in groups. In the copper fcc structure this movement occurs preferentially in any or all of three directions along a specific geometric plane of atoms within the lattice, as shown in Figu...
