The deep drawing test in magnesium alloy sheet AZ31 was executed and the authors discussed the effect of the test conditions (temperature, lubricant, blank holding pressure and processing speed, etc.) on the formability. As a result, we obtained as follows: (1) In the case of lubricant CF-853 added with the Teflon powder, the good states of deep drawing was obtained. (2) A blank holding load of 8OkN was found as a good value to prevent the flange wrinkle. (3) 1mm thickness AZ31 sheets shows poor formability less than 160℃ and shows the good formability at 200℃ for any speed.
