Special Design for Specific Heat Of Nichrome - SGHYZ high temperature electrothermal alloy – Shougang Detail:

BEIJING SHOUGANG GITANE NEW MATERIALS CO.LTD has long been committed to the research and development of electric heating alloy products with good oxidation resistance and high temperature resistance. SGHYZ product is a new product developed after HRE which has been widely used in high temperature electrothermal alloy materials in recent years. Compared with HRE, SGHYZ product has higher purity and better oxidation resistance. With the special rare earth element collocation and unique metallurgical manufacturing process, the material has been recognized by domestic and foreign customers in the field of high-temperature heat-resistant fiber. It has been successfully applied in ceramic sintering, diffusion furnace, high power density and high temperature industrial kiln.
