Ceramic Foundry Sand is made by fusing, spraying, sieving, and purifying high alumina calcined bauxite. They can be used in casting all sizes of steel parts. The spherical shape produces high-density material with excellent flow characteristics, available in a variety of AFS sizes. The main chemical composition is Al2O3 which provides excellent refractoriness and stability.
Nice Foundry Sand (NFS CERAMSITE) is a kind of a new artificial Foundry sand that is ball-shaped, high heat-resistant, low heat dilating rate. NFS has advantage of cost and performance than Chromite sand and zircon sand that provide the effective ways to increase improve the quality of the foundry, cost-down and less damage to the
