This paper describes the tensile properties of magnesium alloy strip produced by melt drag process. Melt drag process is the one of the single roll strip casting process. The thickness of the produced strip at roll speed 5m/min is about 4mm and the width is 60mm. The microstructure of the as-cast AZ31 strip is equiaxed structure and the average crystal grain size is about 80μm. Tensile test at room temperature was applied to examine the mechanical properties of the strip. Tensile strength is 142MPa and the elongation is 10.4% without anisotropy. The n-value is 0.37 and the r-value is 0.88. XRD pattern and (0002) pole figure indicated that the texture of the produced strip had large difference comparing to conventional rolling sheet. These differences may be caused by the randomized texture.
