Material Properties

1. High melting point: The melting point of tungsten is 3422 ℃, and the melting point of molybdenum is 2623 ℃. The alloy formed by the two has a very high melting point, usually between 2600 ℃ and 3400 ℃. This enables tungsten molybdenum alloys to remain solid at high temperatures without melting or deformation.

2. High hardness: The Mohs hardness can reach 7-8, which is higher than many common metals. This high hardness characteristic makes tungsten molybdenum alloy have good wear resistance and can withstand large friction and pressure.

3. Good balance between strength and toughness: Despite its high hardness, tungsten molybdenum alloy is not simply brittle and hard. Through reasonable composition and processing technology, it can maintain a certain toughness while maintaining high strength, relatively less prone to brittle fracture, and reduce the risk of rupture caused by external forces such as impact during use.

4. Excellent corrosion resistance: It has good corrosion resistance to most chemicals such as acids and alkalis, and can exist stably in various chemical environments, ensuring the long-term reliability of material properties.

5. Low vapor pressure: At high temperatures, tungsten molybdenum alloys have a very low vapor pressure and are not easily volatile. This is crucial for components working in high-temperature vacuum environments, as it can prevent material loss and pollution to the surrounding environment.

Difficulties in cutting tungsten molybdenum alloy materials

-High hardness: The Mohs hardness of tungsten molybdenum alloy is 7-8, making it difficult for ordinary cutting tools to effectively cut it, and the cutting tool wears out quickly during the cutting process.

-High melting point: The melting point is usually between 2600 ℃ and 3400 ℃, and the high temperature generated by conventional cutting methods may cause material deformation and cracking.

-Chemical activity: The chemical properties are lively, and it is easy to react with oxygen in the air during processing, resulting in a decrease in material properties and poor cutting surface quality.
