    摘要: A magnesium alloy material for forming which can yield a formed body with high formability without using a lubricating oil or a solid lubricant such as molybdenum disulfide, a magnesium alloy formed body which is obtained by forming the magnesium alloy material for forming, and a manufacturing method of the magnesium alloy formed body are provided. A magnesium alloy material for forming which exhibits a friction coefficient of 0.2 or below at a forming temperature of 350° C. or below is obtained by coating a surface of a magnesium alloy material with an organic resin such as a water-soluble urethane resin, a water-soluble polyester resin, a water-soluble acrylic resin or a water-soluble epoxy resin or a resin obtained by modifying any of these organic resins, or an organic resin formed of any of these resins which contains a silane coupling agent, a colloidal silica, a lubricant, a metal alkoxide or the like. Further, a magnesium alloy formed body such as an automobile part or a container is manufactured by forming a magnesium alloy material for forming.
