The wires used in the wire EDM process are of great importance in this new machining process as the cutting agent of the workpiece. Factors such as the diameter of these wires, their material, and their manufacturing method make their production simply not possible. In the upcoming research, a widely used type of Chinese wire in the domestic industry has been selected, examined, and analyzed. In the early stages of the research, the Chinese wire sample was elementally analyzed and its compounds were extracted, then it was subjected to a tensile test and its mechanical properties were also extracted. In the next steps, the wire was made with the aim of making a Chinese model by two methods of casting and extrusion and was again subjected to chemical analysis and tensile test. Also, in the final stage, all the wires made on the wire EDM machine were put under the same parameters and conditions and tested on a piece of work. The important innovation of the current research is in making wire EDM wire by extrusion method for mass production inside the country. The manufactured wire sample has up to 80% more strength than Chinese wire and is also 10 times softer than that, which increases the strength and softness of the wire leading to greater resistance of the wire and reducing the possibility of its tearing during machining operations.
