Molybdenum (Mo)

Heat resistance · High Thermal Conductivity · Low Thermal Expansion
Compatible with Diffusion Bonding

We introduce machining examples of molybdenum
Molybdenum offers relatively good machinability among refractory metals and is widely used due to its excellent heat resistance and thermal properties.
Materials are stocked in-house, enabling short lead times.
