Product description:

1. This Nice Foundry Sand is a kind of artificial foundry sand. It is mainly made of Al2O3 and is calcined, melted, granulated and selected at high temperatures. NFS is a premium alternative to silica sand and is known as green sand. Its shape is mostly close to a spherical shape, with a smooth surface and a small specific surface area. It has good breathability and good flow, easy to fill and can make the surface perfect. In addition, it can flow very easily and is easy to clean.

2. Nice Foundry Sand's low thermal expansion rate makes it possible to make casting more precise, less cracking and higher yield. Its good crack resistance and high density make it a reusable material and is more beneficial for environments that produce less sand. Its main element is Al2O3, so it has good fire resistance. Its use temperature exceeds 1790 °C. Nice Foundry Sand has a pH of 7.6 and has stable chemical properties. Compared to chromite sand and zircon sand, this product offers cost and performance advantages that provide an effective way to improve casting quality, reduce costs and reduce environmental damage.
