Molybdenum Rod

Pure molybdenum rods are made from high purity molybdenum metal through a precision machining process. Molybdenum is a rare metal with a high melting point, high strength, high hardness, good electrical conductivity and corrosion resistance, making it widely used in high temperature, high pressure and corrosive environments. China molybdenum rod gives full play to these excellent properties of molybdenum and have become an indispensable and important material in many industrial fields.

Pure molybdenum rods Properties:

Ultra-high melting point: The melting point of molybdenum is as high as 2623 ℃, which enables it to maintain good mechanical strength and stability in high temperature environments, and is not easily deformed.

High strength: Pure molybdenum rods have high strength and hardness, which can resist stress at high temperatures and ensure their stable operation in high-temperature environments.

Good conductivity: Molybdenum has good conductivity, which enables it to effectively conduct current and reduce resistance losses.

Good thermal conductivity: Molybdenum conducts heat efficiently, contributing to heat dissipation and temperature control.

Low coefficient of thermal expansion: Molybdenum has a low coefficient of thermal expansion, which makes it less susceptible to dimensional deformation during temperature changes and ensures its stability in high-temperature environments.

Excellent corrosion resistance: Molybdenum has good corrosion resistance in acids, alkalis and other corrosive media, enabling it to work stably for a long time in harsh environments.

Good processability: pure molybdenum rods can be processed through a variety of machining methods, made of different specifications and sizes of products to meet the needs of various applications.

High temperature creep resistance: Under long-term high-temperature loads, pure molybdenum rods have excellent creep resistance and are not easily deformed, which makes them significantly advantageous in applications such as high-temperature furnaces.

Low vapor pressure: At high temperatures, molybdenum has a lower vapor pressure and does not undergo excessive volatilization or loss, ensuring its application performance in a vacuum environment.

Molybdenum rod Surface Finish
Black – Surface is “as swaged” or “as drawn”; retaining a coating of processing lubricants and oxides.
Cleaned – Surface is chemically cleaned to remove all lubricants and oxides.
Ground – Surface is centerless ground to remove all coating and to achieve precise diameter control.

Frequently Asked Questions (FAQ)

Q1: What are molybdenum rods used for?

A1: Molybdenum rods are commonly used in high-temperature vacuum furnaces, semiconductors, glass and ceramic production, aerospace components, and medical imaging devices due to their high melting point, strength, and thermal conductivity.

Q2: What purity grades of molybdenum are available?

A2: FOTMA supplies molybdenum rods in:

• Mo-1 (≥99.95%) – Low impurity, suitable for demanding applications

• Mo-2 – With slightly higher allowable impurities, used in less critical environments

  Each grade meets ASTM standards and is selected based on your purity and performance requirements.

Q3: What is the typical chemical composition of Mo-1 and Mo-2?

A3:

• Mo-1: Impurities (Fe, Ni, Al, Si, Mg, C, N, O) all ≤ 0.01%

• Mo-2: Slightly relaxed limits; Oxygen up to 0.02%, others ≤ 0.01%

  Both grades maintain excellent mechanical integrity and oxidation resistance.

Q4: What sizes and tolerances are available?

A4: Molybdenum rods are available in diameters from 3 mm to 200 mm, with lengths up to 2000 mm or more. Standard tolerances are ±0.05 mm, with tighter tolerances available upon request for precision components.

Q5: Can molybdenum rods be customized or machined to specification?

A5: Yes. FOTMA provides OEM and custom machining services, offering cutting, grinding, polishing, and threading based on customer-supplied drawings or technical requirements.
