CUMI has developed CUMITHERM-Z products for molten ferrous metal handling applications. CUMI uses its own monoclinic zirconia of controlled chemistry and specific surface area along with required additives and control the quality of input raw materials.

CUMITHERM-Z has been designed for extremely harsh environments having extreme wear, corrosion and high temperature characteristics. CUMITHERM-Z products have excellent useful life and extraordinary performance owing to reduced clogging, low erosion and improved surface finish.
