Brass wires start out as a continuously cast 20mm diameter rod. This rod is either cold rolled or cold drawn until it is approximately either a 6mm round or hex cross-section. The wire is then annealed and drawn through a series of dies until it is approximately .9mm diameter. In this state, it is commonly called “re-draw” wire. The re-draw wire is subsequently drawn through another series of diamond dies until it is the final size. At final size, the wire is resistively annealed or thermally tempered in an inert atmosphere, cleaned, and then spooled.
Another variable which determines the ultimate success of the electrode properly EDM Hole Burning through the material or work piece is if the Brass Electrode or Copper Electrode tube has a “single hole” or a “multi channelled hole” running directly through the ID or (Internal Diameter) of the electrode. Basically put; in order for an electrode to perform the way it’s supposed to, it depends on the type of hole going through the centre of the electrode. This type of hole has a few purposes. One purpose is to direct water or coolant through the centre of the electrode. This keeps the entire length of the Brass or Copper Tube from overheating and burning up. If the electrode heats up too much it can become “soft” and warp thus not creating a straight line or a consistent and accurate EDM Hole. The main reason that determines whether an EDM Electrode tube would have a “single hole” or a “multi-channel” “coreless” hole is that when a hole is EDM Machined into a part it could be a “thru hole” or a “blind hole”. Blind holes are not drilled complete to the other side so a “slug” or a piece of material is still left untouched at the bottom of the hole.

Brass electrodes tend to wear out much faster compared to Copper Electrodes, which means the Brass electrode will disintegrate at the point of which the spark leaves the electrode to the point of contact on the work-piece, this should be taken into consideration on long running hole burns or EDM Holes that are very deep.
Conductivity is often expressed as a percentage of IACS, which is a comparison to the conductivity of pure annealed Copper wire (which is the reference standard of 100%). Conductivity is an important property of an EDM wire, since it determines how readily the power
