Chrome Beach Sand

D.D.SHAH MINING PVT LTD ( PT D.D.SHAH MINING INDONESIA) offers superior quality chromite sand to the steel, foundry and refractory industry. At all stages of our supply processes stringent quality control measures are employed to assure that this critical mineral is on target with specification.

Advantages Of Chromite

  • High Density
  • Good For Chilling Casting
  • Prevent Hot Tears

Typical Uses

  • Used to harden steel, to manufacture stainless steel and to form alloys.
  • Used in plating to produce a hard, beautiful surface and to prevent corrosion.
  • Used by the aircraft and other industries for anodising aluminium.
  • The refractory industry uses chromite for forming molds and shapes, as it has a high melting point, moderate thermal expansion, and stable crystalline structure.
