Pure magnesium is a material with very high functionality, however, the cold drawing of this material is very difficult, because it has a hexagonal crystal structure and until this day there is no optimal cold wire drawing conditions. In this research, the goal is to create the optimal cold drawing conditions for pure magnesium wires. The first step is the investigation of the annealing temperatures by using tensile testing of the annealed wires, which will allow is to optimize the manufacturing of magnesium. Following the results listed below, the most suitable annealing temperature was 250°C for a reduction of 10% per pass. After the reaching the drawing limit and examining the drawn wires, cracks in the center of the wires, that is why suppressing their occurrence by applying a middle annealing to the process is needed. Consequently, it is possible to produce a cold fine drawn pure magnesium wire, without cracks or defects on the surface or hindering its medical properties.
