Q&A about Wire Electric Discharge Machining(EDM)

Q What is the difference between HBZ-U and HBZ-MU ?: A

Material composition differs.
EDM wire is made of brass which is an alloy of copper and zinc.
HBZ-U⇒Cu:60％ and Zn:40％
HBZ-MU⇒Cu:65％ and Zn:35％
The more zinc composition EDM wire can have more electric discharge,
resulting in better cutting performance.

Q What is the difference between Paraffin wire and Non-Paraffin wire ?: A

A paraffine wire is that a wire has lubricant paraffin on its surface.
It can help less wire snagging and less brass powder during EDM process.
Our product desicription shows (N) if it is a Non-parrafine wire. (ex.HBZ-U(N)20)
When there is not (N) of its description, it means a Parrafine wire. (ex.HBZ-U20)

Q would like to know the wire length
