Natural diamond (ND)

Natural diamonds (ND) are carefully selected, no impurities, no cracks, high hardness and wear resistance to ensure a long life of the mold.
Natural Diamond (ND) forms naturally in the Earth's crust under high temperature and high pressure. It is the hardest material in known materials. Due to its extremely rigid lattice structure, impurities such as boron or nitrogen can be infiltrated in the formation process.
The natural diamonds we use are strictly selected to ensure their purity.
Natural Diamond Wire Drawing Die is made of high quality punching core, which has the advantages of uniform structure, strong wear resistance, high finish, high precision and long service life. It can ensure the surface finish and accuracy of wire rod and production range of mold inner diameter in the long drawing process 0.008mm-2.00mm.
Natural Diamond is the material with the best surface finish of all materials. Its high hardness and wear resistance ensure the longevity of the matrix.
