Diamond is known as the hardest material in the world, has the extremely high degree of hardness and the good thermal conductivity and the light thermal properties, widely applies in the industrial field in the tool manufacture, in optics product and the conductor profession.
Usually as the wired rawing dies raw material's diamond is the la diamond. This kind of diamond includes certain nitrogen impurity (0.1% magnitude), and these nitrogen impurity set has become the very small aggregate. Simultaneously also includes the small piece (in nitrogen impurity relation), at present these small piece precise structure unknown.
This factory production's rough diamond wiredrawing mold selects material from the high quality natural diamond material, undergoes the strict choice, the processing becomes. The surface smooth finish is high, the resistance to wear good is its principal advantage. Is suitable requests the high each kind of wire rod in the surface quality the drawing.
dies size range: 0.015mm~2.00mm
