Drawing monocrystalline mandrel

Single crystal diamond drawing die core for a variety of hot and cold-drawn metal filaments pull, it is highly brushed finish, long life. Reasonable prices so that the single crystal diamond Drawing core become drawn a variety of high-end products the ideal choice. Diamond is a single crystal of carbon atoms, the crystal structure belonging to an isometric face-centered cubic (the highest density of an atomic crystal). Since the linkages between carbon atoms in diamond is sp3 hybrid covalent bond, it has a strong binding force, and directional stability. It is the hardest substance known to nature, its hardness up 10000HV. Artificial single crystal diamond and natural diamond has not only comparable to a good performance, but also with natural diamond impossible isotropic, high hardness, wear resistance, high strength, good thermal conductivity, coefficient of friction and non-ferrous metal low, anti-adhesion, good corrosion resistance and excellent chemical stability, especially in the field of mechanical processing of ultra-precision machining field has an important position and has been widely used. For single crystal diamond itself, the physical characteristics of good manufacturing tool surface quality, surface finish, is the ideal material for drawing die.
