The non-combustible Magnesium alloy was developed by the present authors. The ignition point was raised to 1 000 K by adding calcium in this material. In this report, specification of a fatigue crack origin and N=107 fatigue strength of 3 kinds of non-combustible Mg alloy was discussed. Consequently, it was clarified that fatigue crack origins of all materials are inclusions and that the material containing more Al is higher N=107 fatigue strength. Moreover, the fatigue strengths at N = 107 of these materials were successfully estimated on the basis of the inclusion size distributions in the material.
