High-Temperature Casting Compounds
Capture intricate details when creating prototypes, molds, and linings with these easy-to-mix compounds.
Alumina is high strength.
High-purity alumina resists shrinking in casts, has a low level of contamination, and is a strong electrical insulator. It’s often used for constructing furnaces and handling liquid metal.
Silicon carbide has a high heat transfer rate, making it ideal for use in metal casting molds. It has the added benefit of excellent erosion and oxidation resistance.
Silica withstands rapid changes in temperature without cracking and has a low rate of thermal expansion.
Zirconium oxide is often used in metal handling applications. In addition to its high temperature resistance, it’s also chemical resistant.
