A method for producing a magnesium alloy having improved mechanical and electrochemical properties. The method includes generating a high-purity magnesium by vacuum distillation. A billet of the alloy is generated by synthesis of the high-purity magnesium with 2.0 to 10.0% by weight Al, the remainder being magnesium containing impurities, which promote electrochemical potential differences and/or the formation of precipitations and/or intermetallic phases, in a total amount of no more than 0.0063% by weight of Fe, Si, Mn, Co, Ni, Cu, Zr, Y, Sc or rare earths having the ordinal numbers 21, 57 to 71 and 89 to 103, Be, Cd, In, Sn and/or Pb as well as P, wherein the matrix of the alloy includes intermetallic phases formed of Mg and Al. The alloy is homogenized by annealing at a temperature between 150° C. and 450° C. The homogenized alloy is formed in the temperature range between 200° C. and 400° C.

The invention relates to biomimetic, biodegradable composites including a magnesium (Mg) alloy mesh and a polymer/extracellular matrix (ECM). These hybrid composites, more particularly, are useful for the fabrication of medical implant devices, e.g., scaffolds, and are effective for bone regeneration. The fabrication process includes creating the Mg alloy mesh, and concurrently electrospinning the polymer and electrospraying the ECM onto the mesh.
