What Is the Drawback of Molybdenum High Temp Heating Element?

One of the drawbacks of molybdenum high-temperature heating elements is their relatively low ductility and low-temperature brittleness. At temperatures below 400°C, molybdenum becomes brittle and prone to cracking when subjected to mechanical stress. This can limit its use in certain applications that require high-temperature stability combined with mechanical durability. Additionally, molybdenum has relatively poor oxidation resistance, which can limit its lifespan and performance in some high-temperature environments.
