Types of wires for EDM machine

There are two main types of wire used for the main wire for EDM machine, brass wire and coated wire.

(1) General-purpose brass wire

Brass is an alloy of copper and zinc and has excellent discharge characteristics.
These discharge characteristics improve as the zinc content of the brass increases. However, it becomes difficult to form high zinc-content brass into a thin wire, because the malleability of the brass is reduced.
Brass with 35% to 40% zinc content is widely used, considering the balance between product performance and machining characteristics.

(2) Coated wire

A number of the characteristics of the single-layer structure have limitations. The coated wire has functionality that overcomes these limitations.
Currently, the main types of coated wire on the market are zinc-coated wire and diffusion-annealed wire.
