Chromite sand is a high‑refractoriness, low‑expansion, high‑thermal‑conductivity mineral sand widely used across foundry, refractory, metallurgy, glass, ceramics, construction, and friction materials.

325-mesh chromite flour is a premium, performance-enhancing material used primarily as a refractory coating in steel foundries to achieve superior casting surface quality and as a fine aggregate in advanced refractory bricks and monolithics for high-temperature industrial furnaces.

Chromite flour is a specialized, problem-solving refractory material. Its core application is to serve as a highly stable, chemically inert, and thermally conductive face-coat material in the investment casting of reactive high-temperature alloys and as a high-performance mold wash in sand casting of demanding steels.

For alloy steel foundries, chromite sand is a premium problem-solver. Its combination of chemical inertness, high chilling power, and thermal stability makes it the material of choice for preventing penetration defects, improving internal quality, and enabling the production of sound, high-integrity alloy steel castings.

Foundry Grade Chromite Sand (46% Cr₂O₃) is a high-performance, refractory aggregate of choice for solving thermal expansion, burn-on, and metal penetration defects in demanding ferrous castings.

Chromite sand originating from South Africa is a benchmark product in the global foundry industry. it is a naturally occurring spinel consisting primarily of the oxides of chrome and iron
