What Is the Best Molybdenum Wire for EDM Cutting? A Buying Guide
In the case of a wire-cut EDM machine, the speed at which you will be able to cut depends on the wire itself, the surface finish, and how often you will have to experience wire breakage in the middle of your job. For slow-speed and fast-speed wire-cut EDM, the most common electrode wire used is molybdenum wire. Molybdenum wire can resist repeated spark discharge much better than brass wire, and it is not as costly as tungsten wire for the same work. However, the term "molybdenum wire" is not a single spec; the diameter, the purity, and the surface finish all affect its performance, and the wrong combination results in slower cuts, wire breaks or a finish that is not as smooth as that needed for the job. This guide explains which molybdenum wire spec is used in which EDM application, what the purity of each wire is and what this term actually means to the cutting results, and what to look out for when purchasing from Molybdenum Wire Manufacturers.
