• High-Temperature Stability: Molybdenum has a very high melting point, reaching 2623K (2350°C), making molybdenum screws exhibit excellent performance and stability in high-temperature environments.
• Corrosion Resistance: Molybdenum has good corrosion resistance and can withstand the corrosion of most acids and bases. This makes molybdenum screws suitable for use in chemically harsh environments.
• High Hardness and Wear Resistance: Molybdenum has higher hardness, hence the screws made from it have higher wear resistance, suitable for long-term, high-strength working environments.
• Oxidation Resistance: In high-temperature environments, molybdenum can form a stable oxide layer, which helps improve its oxidation resistance and extend the lifespan of the screws.
• High Strength and Toughness: Molybdenum has high strength and toughness, maintaining good mechanical properties even in extreme environments.
• Low Coefficient of Thermal Expansion: Molybdenum has a lower coefficient of thermal expansion, meaning its volume changes less with temperature variations, which is very important for some precision devices and high-temperature applications.
• Good Electrical Conductivity: Molybdenum has good electrical conductivity, making molybdenum screws also suitable for electronic and electrical applications.

1. High-Temperature Environments: Molybdenum screws exhibit superior performance in high-temperature environments, making them commonly used in aerospace, aviation engines, rockets, spark plugs, high-temperature furnaces, and other high-temperature industrial applications.
2. Vacuum Systems: The use of molybdenum screws in vacuum systems is due to their chemical stability and low volatility. They are typically used in the manufacture of vacuum-sealed systems, vacuum furnaces, and other equipment requiring a stable vacuum environment.
3. Nuclear Applications: Molybdenum screws can be used in nuclear reactors, nuclear power plants, and other nuclear applications, as they can withstand high radiation and high-temperature environments.
4. Semiconductor Industry: The high conductivity and chemical stability of molybdenum screws make them suitable for use in semiconductor manufacturing equipment, such as in plasma etching machines and thin-film deposition equipment.
5. Chemical Industry: Due to the corrosion resistance of molybdenum, molybdenum screws can be used in the chemical industry, especially in equipment handling corrosive chemicals.
6. Optics and Laser Systems: Molybdenum screws are used in some optical and laser systems, such as high-power laser equipment, where they need to withstand high energy output and high temperatures.
7. Thermal Dissipation Materials: Molybdenum has good thermal conductivity, so in applications requiring heat dissipation, such as cooling systems for high-power electronic components, molybdenum screws can be used as thermal dissipation materials.
8. High-Performance Mechanical Structures: Although molybdenum is a brittle material, its strength can be improved in certain shapes. Therefore, in some mechanical structures requiring high temperature and high strength, molybdenum screws can play a role.
