Product Overview

Key Features

We are engaged in distributing, exporting and supplying excellent quality High Refractoriness of Yuanyang Nice Foundry Sand to our valuable clients. Yuanyang Nice Foundry Sand(NFS) is made from high quality bauxite, melt formed by high-temperature furnace. NFS is of spherical particles shape, the main ingredient is an alumina (Al2O3) with refractoriness up to 1790 a . The refractoriness of Nice Foundry Sand is comparable with chromium ore, NFS are now replacing chromium sand in the casting field.

The main component of quartz sand is silicon dioxide (Si02), which is has lower refractoriness of 1700 a . For NFS in casting field, different crystals will appear in a variety of different temperatures. Thereby it reduces its refractoriness the again during casting process.
