1. Good ware resistance
2. Excellent polishing
3. Small adhesion
4. Small friction coefficient
5. High coefficient of thermal conductivity
6. Good corrosion resistance
The hole of the wire drawing dies is made up of four parts:
*Lubricating area of the entry: There is an arc to make the wires enters to the workaround conveniently.
*The workaround: The metals come about plastic deformation while drawing, the cross section of the metals is compressed and reduced.
*Diameter fixed district: to guarantee the size and form accurate and even, lengthen the service life of the die.
*Wire outlet area: wire outlet terminal can prevent scuffing and break-up when the machine is stopped.
