Chromite

We offer a superior quality chromite sand for the steel, foundry and refractory industries. At all stages of our supply process, stringent quality control measures are employed to assure that this critical mineral is on target with specification.
Chromite, as is indicated by its early crystallization, is resistant to the altering affects of high  temperature and pressures. These characteristics explain the use of chromite as a heat conductive foundry molding sand, which allows localized or general chilling of castings to improve their integrity.

Advantages of Chromite

• high quality
• 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 anodizing aluminum
• the refractory industry uses chromite for forming molds and shapes, as it has a high melting point, moderate thermal expansion, and stable crystalline structure
