ZTC71 Series Matrix powders for PDC bits

  • ZTC71 series matrix powder mainly consists of Marocrystalline Tungsten Carbide and Nickel powder. After special treatment, control, and screening, the different powders are prepared according to customer application requirements and used primarily for infiltrating high-performance PDC drill bits and parts, TC bearings.
  • ZTC71 matrix powder has good wear resistance, corrosion resistance, impact resistance, and a high penetration absorption value.
