It is generally believed that pure metals have high plasticity and good plasticity when other alloying elements are added to form a single-phase solid solution. The plasticity decreases when the elements are added to form compounds. Face centered cubic crystals, such as Cu, Al, Ni, Pb, Au and Ag, have higher plasticity. The plastic times of BCC crystals, such as Fe, Cr, W, Mo, and beta brass, etc. Low plasticity is the six party lattice metals, such as Zr, Hf, Ti and so on.
