Features & Benefits

Base Chemicals Features
Features
  • Compressibility - This can be single-pressed to densities up to 7.0 g/cm3.
    • Higher strength, higher density parts extend the performance range of sponge iron applications.
  • High green strength - This assures powder performs of good structural integrity.
    • Improves thin section integrity and facilitates green parts handling.
  • Low growth characteristics - the high purity and large specific surface area of this allows for rapid sintering and greater dimensional control.
    • Reduces sintered dimensional variation.
    • Improves dimensional control of copper infiltrated parts and blends containing copper.
  • Consistency - a stable ore base and statistically controlled manufacturing process assure lot-tolot consistency.
    • Improves P/M part consistency.
