Molybdenum Rods

Product Description

Molybdenum rods are formed into rods, after the refractory metal molybdenum is sintered. Thereby, they acquire the metal’s significant properties. High melting and boiling point, robustness, high resistance to corrosion and high temperatures, low thermal expansion etc, are the qualities that it possesses, which makes it a beneficial product.

Molybdenum rods can then further be used to manufacture wires, small crucibles and tubes, electrodes, ingots (rods that have a larger diameter than the standard rod size) etc. Generally, lanthanated molybdenum rods are used for high temperature functions as it retains its high ductile property after the rods are recrystallised.

Molybdenum rods are produced at random lengths which are then cut into the required sizes. It comes in three types of surface processes, they are: –

Black-surface – these are coated with lubricants and oxides used for production process

Clean-surface – the processing lubricants and oxides are cleaned chemically

Ground-surface – the coatings are removed, with the focus on getting specific targets diameters.

Key Features

Molybdenum is a refractory material that can withstand high temperatures, even higher than steel and nickel alloys. Due to its oxidation at low temperatures, it is best to use Molybdenum Crucibles in vacuum. Significant features include –

• High purity
• High creep resistance
• High dimensional stability
• Low co-efficient of thermal expansion
• Good thermal conductivity
• Good electrical conductivity
• Good stiffness, greater than that of steel
• High melting point (2622 °C)
• High boiling point (4639 °C)
• High red-hardness
• Good strength and ductility
• High density

Applications

Molybdenum rods can be shortened and reformed into other molybdenum products which increases its diversity in applications, they are used: –

• As additives for steel-making process
• As Electrode, Stirring Rod, Protective Cover for manufacturing variety of glass products such as regular drinking glass, optical glass, glass fibre (Tungsten and Platinum are very expensive for this application)
• To make electric vacuum parts
• To make gas pipes
• To reshape it into wires, electrodes, tubes and small crucibles

Molybdenum rods are commonly used in various industries, like:

• Furnace Manufacturing
• Heater Manufacturing
• Electrode Manufacturing
• Automotive
• Aerospace
• Metal Industry
• Metallurgy
• Stainless steel and Steel Industry
• Solar Cell
• Fuel Cell
• Energy Storage
• Nanotechnologies

Frequently Asked Questions:

What is the material used to make molybdenum rods?

Molybdenum rods are made from high-purity molybdenum metal, a refractory metal known for its excellent strength, high melting point, and resistance to corrosion and thermal expansion. This makes molybdenum rods ideal for use in high-temperature industrial and scientific applications.

What are the available shapes and sizes of molybdenum rods?

Standard molybdenum rods come as round bars with diameters from 0.5 mm to 120 mm and lengths up to 1000 mm or more. Many suppliers—including your preferred molybdenum rods supplier—also machine them into square or custom profiles on request.

What industries use molybdenum rods?

Molybdenum rods serve wherever extreme heat and mechanical reliability are essential: aerospace, defense, semiconductor fabrication, glass and LED production, and high-temperature furnace components. Molybdenum rods suppliers often tailor grades to each sector’s specific needs.

What is the maximum temperature molybdenum rods can handle?

In vacuum, molybdenum rods remain stable up to about 2900 °C, and in inert atmospheres up to 1900 °C. This ultra-high refractoriness makes them ideal for the most severe thermal environments.

Are molybdenum rods resistant to corrosion?

Yes, molybdenum rods resist corrosion in non-oxidizing and acidic media at elevated temperatures. However, they oxidize rapidly above 600 °C in air, so a protective inert atmosphere or vacuum is recommended for hotter applications.

Can molybdenum rods be machined or welded?

Absolutely, You can machine molybdenum rods using carbide tooling, and weld them under argon or another protective gas. Your molybdenum rods supplier can provide guidance on best practices to avoid oxidation and cracking during fabrication.
