High-Temperature Molybdenum Plate

High-Temperature Molybdenum Plate is a flat-rolled molybdenum product designed for extreme thermal, vacuum, and corrosive environments. Thanks to molybdenum’s high melting point (2620°C), excellent thermal stability, low vapor pressure, and good creep resistance, molybdenum plates are widely used in high-temperature furnaces, semiconductor equipment, aerospace components, and advanced energy systems.

Our molybdenum plates are manufactured from high-purity molybdenum powder through powder metallurgy, followed by hot rolling and controlled heat treatment, ensuring uniform grain structure, stable mechanical performance, and reliable service life under demanding conditions.
