OHMPM145 Strip
(Common name: Kanthal APM)
Ohmalloy Material Co., Ltd. has long been committed to research and development of electrothermal alloy products with good oxidation resistance and high temperature resistance. OHMPM145 alloy is a new product developed after HRE alloy which has been widely used in high temperature electrothermal alloy materials in recent years. Compared with HRE, its purity and oxidation resistance is further improved and optimized. With special rare earth elements and unique metallurgical manufacturing process, OHMPM145 has been recognized by customers in the field of high temperature heat-resistant fibers around the world. It has been successfully applied in ceramic sintering, diffusion furnace, high power density and high temperature industrial kiln.
