CastTherm®CR Chromite for Improved Molding and Casting Properties
CastTherm foundry grade chromite is used for its unique properties, high thermal conductivity, high heat resistance, low thermal expansion, and high cost-effectiveness.
In partnership with Rand York, HA-International, LLC., introduces CastTherm Chromite to the North American foundry market. Rand York Minerals is one of the largest and independently owned foundry chromite ore suppliers globally and the partnership will ensure consistent supply to the market. The material is mined from the principal chromite Ore deposits in South Africa and is produced under high-quality standards to sustain improved molding and casting properties in using the CastTherm Chromite.
Our high-quality CastTherm Chromite product is available in multiple grades from 45 to 80 GFN. The controlled mining, multi-stage cleaning, drying, screening, and packaging into bulk bags ensure for low moisture, consistent screen distribution, and low turbidity.
The benefits of CastTherm CR Chromite
Available GFNs - 45, 60, and 80 with normal distributions whether for heavy sections or when finer surface finish is needed for intricate detail
Availability of the finer grades offers a lower cost option compared to zircon and ceramic
Double-bagging to ensure product is kept dry while minimizing handling and segregation
High chromium oxide chemistry maximizes a high rate of heat transfer providing excellent chilling characteristics
Low silica content <1%, ensuring consistent sinter points for heavy section applications
Low turbidity, indicating a cleaner substrate
Eliminates veining and improves casting surface finish
CastTherm 45 is used for molding and ingate area applications where high thermal conductivity, heat resistance, and high dimensional stability is critical.
CastTherm 60 and 80 Chromite are used for ferrous and non-ferrous molding applications where high thermal conductivity, heat resistance high dimensional stability and casting surface finish is critical.
