Product Features
1.Excellent high-temperature resistance
Molybdenum has a melting point as high as 2620°C, and molybdenum bolts can stably operate in long-term high-temperature environments ranging from 1600°C to 1800°C without deformation or strength degradation, making them suitable for high-temperature systems such as vacuum furnaces, single crystal furnaces, and LED equipment.
2.High Purity and High Strength
Industrial-grade molybdenum bolts typically have a purity of >99.95%, a density of ≥10.15 g/cm³, and exhibit high hardness along with excellent physical strength, enabling them to withstand heavy loads and high-pressure environments.
3.Low thermal expansion coefficient
Molybdenum has a low thermal expansion coefficient, resulting in minimal dimensional changes when heated, ensuring a tight and sealed connection even under extreme temperature fluctuations to prevent loosening or leakage.
4.Good corrosion resistance
Although molybdenum has lower corrosion resistance than titanium at room temperature, it exhibits strong chemical inertness in high-temperature inert or vacuum environments, demonstrating good stability against acidic, alkaline media, and oxidative gases.
5.Excellent conductivity and thermal properties
Molybdenum possesses excellent electrical and thermal conductivity, making it suitable for secure connections requiring heat dissipation or electrical conduction in electronic and semiconductor equipment.
6.High degree of customization
Customization is available based on drawings or samples for various specifications (M2-M40 and above), head types (hexagon, countersunk, etc.), and surface treatments (alkali cleaning, polishing, etc.), meeting special equipment assembly requirements.

The applicable environment of molybdenum material: vacuum environment or inert gas protection environment, pure molybdenum can withstand high temperatures up to 1200 ℃, and molybdenum alloy can withstand high temperatures up to 1700 ℃.
Molybdenum bolts still have good physical strength above 1700 degrees and are widely used in vacuum furnaces, single crystal furnaces, LED furnaces, glass ceramics, and other equipment.
FAQ
Q: 1. What are the advantages and disadvantages of molybdenum screws?
A: The advantages of molybdenum screws include high melting point, excellent corrosion resistance, and low thermal expansion coefficient. They are widely used in industries that have to withstand high temperatures, high pressure, and corrosive environments.
These fasteners are particularly useful in aerospace, nuclear energy, high-temperature industrial furnaces, and chemical equipment because they can maintain mechanical stability and structural integrity under extreme conditions.
The unique physical and chemical properties of molybdenum make it an ideal choice for handling demanding applications. However, molybdenum screws also have some potential disadvantages or limitations.
1. Expensive: The raw material of molybdenum screws is molybdenum, which is a rare metal with a relatively high price, so the cost of molybdenum screws is also high.
2. Poor toughness: Molybdenum screws have relatively poor toughness and are prone to brittle fracture.
3. High-temperature creep: Long-term use at high temperatures may cause creep, resulting in dimensional changes.
4. Sensitive to temperature: Molybdenum screws are sensitive to temperature changes and are prone to thermal expansion and contraction.
5. Difficult to process: Due to the high hardness of molybdenum, the processing difficulty is high, and higher processing technology and equipment are required.

Q: 2. Where are molybdenum bolts generally used?
A: Molybdenum screws are a special fastener. Due to their excellent high-temperature resistance, they are widely used to fix mechanical parts that need to withstand high-temperature environments. These parts include but are not limited to fasteners for sintering furnaces, ensuring that these parts can remain stable in high-temperature environments and will not be damaged or degraded due to high temperatures. In addition, molybdenum screws are also used in civilian fields, such as vacuum furnaces, single crystal furnaces, LED furnaces, glass ceramics, and other equipment, to fix and connect key components in these equipment to ensure that they can operate stably during work.
Q: 3. How high a temperature can molybdenum screws withstand?
A: Molybdenum screws can withstand temperatures of up to 1600°-1700° or more. Molybdenum screws are made of high-quality molybdenum raw materials with a purity of more than 99.95%. This material has excellent high-temperature resistance and can maintain stable working performance in extremely high-temperature environments.
The implementation standard of molybdenum screws is GB/T5782-2000. Its specifications range from M1.6 and above. The surface has bright characteristics and is in a cold-processed state. It is made by machining methods. The high-temperature resistance of molybdenum screws and nuts makes them widely used in vacuum furnaces, single crystal furnaces, LED furnaces, glass ceramics, and other equipment in the fields of aviation, aerospace, scientific experiments, and civil use.
