Notes:   Volume susceptibility χV in SI is related to cgs molar susceptibility χm by:  χV =4πd χm /(M.wt.).

Measured χV on commercial material at 7 T, 300 K.  

Susceptiblity is much higher at lower fields and lower temperatures for materials containing iron, cobalt, or nickel. Yield strength for metals given for annealed condition with ~10% cold work except for brittle materials.  

Elongation given for annealed condition.  

Strength of quartz and pyrex varies from 1/3 listed values to three times listed values depending on time under stress and surface conditions.
