Grade III Foundry Sand High Refractoriness With Low Thermal Expansion Coefficient

Grade III Mullite Sand of Foundry Sand for Precision Casting Materials and Refractory Products Material

1. Brief introduction of our company 

  In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also cooperate with mining companies to develop customized products. Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

  It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.

2. Product description

Mullite sand of foundry sand is a kind of aluminosilicate refractory material. It is made of hard clay mineral resources by high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes. It has high aluminum content, low iron content, small coefficient of thermal expansion, high refractoriness, stable thermochemical properties and other excellent mullite series sands and powders.
