Hitachi Metals' SIALON is ideal for tools that contact molten aluminum on the aluminum melting and casting line. SIALON has high density and keeps high strength within the temperature range of molten aluminum; and moreover, SIALON shows no corrosion from molten aluminum. It has excellent chemical stability and prevents molten aluminum contamination. These features provide cost-effective performance through long life and reduced maintenance.
Hitachi Metals developed SUPER-SIALON that surpasses even SIALON in strength and thermal shock resistance. This new ceramic material is expected to be used, not only as tools that contact molten aluminum with more severe conditions, but as tools in steelmaking related devices such as continuous galvanizing line.
