Molybdenum rods generally exhibit better stability under temperature changes. Due to the low thermal expansion coefficient and high melting point of molybdenum rod, it can maintain relatively stable size and performance in the environment of temperature changes.
Thermal expansion is the dimensional change of a material due to the influence of heat when the temperature changes. Molybdenum rods have a low coefficient of thermal expansion, which means that when the temperature changes, the dimensional changes of molybdenum rods are relatively small. This enables the molybdenum rod to maintain a relatively stable shape and size under temperature changes, avoiding stress and deformation due to thermal expansion.
In addition, molybdenum rod has a high melting point (approximately 2,620°C), which means it maintains structural stability in high-temperature environments. It is able to withstand higher temperature changes without significant shape change or damage.
