Pointing auxeticity surfaces of Be, Zn, MoS2, MnAs, TiB2 and BeCu (2,4 atm. % Cu) single crystals of hexagonal system were plotted for the first time using the experimental values of the elastic modulus , which given in the tables Landolt-Bernstein. The criteria of appearance of axial and noaksial auxeticity were established. The influence of alloying and temperature on effects of Be abnormal deformation was detected. The mechanisms of auxeticity properties formation in hexagonal crystals were established.
