Import Chrome Sand Afs45-55 — Buy in Bulk from Supplier in South Africa

The Chrome Sand AFS45-55 supplied by Optimin SA is an industrial abrasive designed for foundry and metalworking moulds. It is produced in South Africa and conforms to the AFS45-55 grade used in sand casting. The sand offers a consistent grain size distribution that supports uniform mould strength. Chemical stability prevents adverse reactions during the melt.

Typical grain sizes for the AFS45-55 class range between 45 and 55 µm, providing a balance between surface finish and permeability. Its high thermal resistance, commonly up to 800 °C, allows it to withstand the temperatures of steel and aluminium casting. Angular particle shape improves compactness, while moisture content is kept below 0.5 % to avoid steam defects. These characteristics align with standard specifications for chrome sand used in automotive and aerospace casting.

Foundries producing automotive engine blocks, aerospace components or heavy‑machinery parts frequently choose this sand for its repeatable performance. Importers can order in bulk, with the supplier indicating a flexible minimum order quantity that should be confirmed directly. Shipping is offered under CIF or FOB terms from the port of Durban, and the sand meets export quality standards verified by relevant authorities.
