High-quality precision in foundries.
Perfect for metal casting applications.
MinSand is a perfectly spherical refractory bead produced by melting high-purity Bauxite in an electric arc furnace. The molten material is then rapidly supercooled to form uniformly round particles with excellent thermal stability, hardness, and flow properties, ideal for high-performance industrial applications.
MinSand is a specially processed ceramic sand designed for industrial applications such as foundries and mould casting. Known for its thermal stability and uniform grain size, MinSand is ideal for creating precise moulds and casting high-quality products. 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.
Our MinSand mineral can be supplied in Europe and the UK.
This material can 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 1000kg bulk bags and 25kg paper bags.
MinSand is a high-performance spherical ceramic 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.
