High-quality precision in foundries.
Perfect for metal casting applications.
MinSand is a perfectly spherical refractory bead produced by fusing and supercooling Bauxite in an electric arc furnace.
Minsand is a specially processed silica sand designed for industrial applications such as foundries, construction, and mold casting. Known for its thermal stability and uniform grain size, Minsand is ideal for creating precise molds and casting high-quality products. In construction, it is used in concrete and other building materials to improve strength and stability. With its high purity and consistent performance, Minsand from LKAB Minerals is a trusted choice for applications where quality and reliability are of great importance.
emperature, enabling the material to be used to replace alternative and more expensive moulding and core making sands. Castings can therefore be produced in steel, high duty iron and non ferrous metals.
MinSand is available in the following grades:
| G Grade |
|---|
| AFS 50 |
| AFS 65 |
| AFS 90 |
Please get in touch with your local sales representative for further information.
Regular packaging modes for our product are 1,000 kg big bags and 25 kg paper bags.
MinSand is a high-performance spherical silica sand used in foundry applications for its superior flowability, low thermal expansion, and compatibility with various resin systems. Some key applications include:
| Bulk density [g/cm³] | 1.9 |
| pH | 7.5 |
| Particle shape | Spherical |
| Colour | Brown-black |
| Al2O3 [%] | 75.9 |
| Fe2O3 [%] | 1.59 |
MinSand has several properties that make the product quite unique on the market:
The spherical particle shape significantly improves the flowability of the sand/binder mixture allowing cores of complex shapes to be blown when compared to alternative angular sands.
It has a very low thermal expansion rate, which enables castings to be produced with a high degree of dimensional accuracy compared to mould and cores produced from alternative sands. This is eminently suitable for automotive cylinder blocks and heads.
The spherical nature results in a reduced surface area, enabling cores and moulds to be produced using lower resin additions. The mixed sand costs are reduced accordingly because of the lower resin demand.
LKAB Minerals’ product is compatible with resin systems, including pre-coated shell moulding sands. The sand grains have a very smooth surface that is easily resin coated.
