Graphene-loaded grain refinement material of Al-Mg alloy wire and preparation method of graphene-loaded grain refinement material

The invention discloses a graphene-loaded grain refinement material of an Al-Mg alloy wire and a preparation method of the graphene-loaded grain refinement material. The graphene-loaded grain refinement material is prepared from, by weight percentage, 0.10%-0.20% of Gp, 0.10%-0.20% of V, 0.10%-0.20% of Zr, 0.20% of Mn, 0.20% of Ti, 0.40% of Fe, 0.08% of Si, 0.20% of Cr and 0.40% of Cu. The preparation method comprises the following steps of uniformly mixing intermediate grain refined alloy, and afterwards, conducting briquetting, sintering and annealing, mechanically alloying and melting. Thatis to say, other component materials except aluminum and magnesium are subject to sintering and ball-milling, and then briquetting, and are then put into an aluminum and magnesium solution. By meansof the preparation method, the strength and conductivity of the aluminum-magnesium alloy wire are improved, the wire breakage rate and fineness of the wire are reduced, and the material performance ofthe aluminum-magnesium all
