FeCrAl OHMPM145 Wire Used in Ceramics Kiln Electric Furnace 1400℃ Heating Element Wire
OHMPM145 alloy is a new product developed after HRE alloy which has been widely used in high temperature electrothermal alloy materials to replace the material APM 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.
