NOVELTY - The preparation method of magnesium alloy involves adding 5-10% graphene-containing dispersant to 100 mu m aluminum powder and then mixing, drying the mixture and then molding, heating the mixture at 700-750 degrees C and then continuously stirring at 700-750 degrees C for 30-60 minutes, heating the mixture and then casting, heating the mixture at 700-800 degrees C for 10-30 minutes and then continuously stirring, leaving the mixture for 30-60 minutes and casting. USE - The method is useful for preparation of magnesium alloy. ADVANTAGE - The method enables economical preparation of magnesium alloy with excellent stability, corrosion resistance, fatigue resistance, strength, creep resistance and mechanical properties.
