Description of Molybdenum Head Mandrel
Molybdenum is a silver-white refractory metal that is more ductile and ductile than the metal tungsten. Molybdenum head is made of molybdenum powder and a small amount of rare earth materials, which are processed by mixing, forming, rolling, and high-temperature sintering. Molybdenum Head Mandrel is a good thermal conductor with a high melting point, high corrosion resistance, low resistivity, low thermal expansion coefficient, excellent creep resistance, good high-temperature oxidation resistance, and long service life.
Molybdenum Head Mandrels are often used for hot rolling and piercing of seamless steel pipes, such as brazing steel, high temperature alloy steel and stainless steel. Molybdenum heads are also widely used in semiconductor materials, light source materials, electric vacuum devices, and heating elements in high-temperature furnaces. In addition to high-quality molybdenum heads, our company can also provide other molybdenum products, such as molybdenum machining parts, molybdenum crucibles, molybdenum boats, and molybdenum rods.
Features of Molybdenum Head Mandrel
1. Ultra-High-Temperature Stability
With a melting point as high as 2610°C, it can operate for extended periods in high-temperature environments between 1200°C and 1800°C (e.g., glass softening and crystal growth).
High-Temperature Strength Retention: Tensile strength >100 MPa at 1500°C, preventing bending or deformation.
2. Low Thermal Expansion & Dimensional Stability
The thermal expansion coefficient is 5.8×10⁻⁶/°C, close to that of ceramic materials, reducing dimensional deviation caused by thermal stress.
No deformation at high temperatures: Suitable for precision forming processes (e.g., fiber drawing).
3. Corrosion Resistance
Resistant to molten glass and metal vapors (e.g., aluminum and copper), its lifespan far exceeds that of stainless steel mandrels.
Resistant to acidic and alkaline atmospheres (e.g., fluoride vapor), it is suitable for specialized glass processing.
4. High Surface Finish
Roughness Ra <0.4μm after polishing, preventing adhesion to melt or fiber materials.
Low coefficient of friction: Reduces friction losses with materials (such as optical fiber coatings).
Applications of Molybdenum Head Mandrel
1. Glass and Fiber Optic Manufacturing
Fiber preform drawing: Molybdenum mandrels serve as support cores, resistant to temperatures up to 1600°C (e.g., Corning fiber production lines).
Specialty glass tube molding: Guides the flow of molten glass (e.g., borosilicate glass, quartz glass).
2. Single Crystal Growth
Sapphire (Al₂O₃) crystal growth: Molybdenum mandrels are used in the EFG (edge-confined film growth) method.
Silicon carbide (SiC) single crystals: Resistant to high-temperature steam corrosion up to 2200°C.
3. High-Temperature Forming and Sintering
Ceramic dry pressing: Serves as mold mandrels, resistant to high-temperature sintering (e.g., Al₂O₃ and ZrO₂ ceramics).
Powder Metallurgy: Supports the high-temperature HIP (hot isostatic pressing) process.

benefits of Molybdenum Head Mandrel
Temperature Resistance: Molybdenum boasts a very high melting point, greater than 2,600°C, making it extremely temperature-resistant. This means that our Molybdenum Head Mandrels would not lose their shape and strength under intense heat, which is highly necessary in applications such as high-temperature manufacturing, metal forming, and vacuum furnaces.
Excellent strength and toughness: due to the great strength of molybdenum, it features outstanding resistance to both mechanical wear and plastic deformation. Thus, it provides that within several cycles, the mandrels do not lose their performance and shape under the stress of heavy loads or in a high-pressure environment.
Oxidation and Corrosion Resistance: Molybdenum has very good resistance to oxidation and corrosion, especially at higher temperatures. For this reason, our Molybdenum Head mandrels are seldom found with any sort of failure while operating in a surrounding of reactive gases or high oxygen atmospheres, which might be the case with high-temperature furnaces or vacuum systems.
Precision and Customization: We manufacture molybdenum head mandrels with extreme precision. With the capability for custom sizing, shapes, and surface finishes, we can provide a perfect fit for your unique manufacturing or fabrication need. Whether you require mandrels in small batch production or large-volume runs, we can provide tailored solutions.
Excellent thermal conductivity: Molybdenum has a very high thermal conductivity, and what this means is that, within the mandrel, there is even dispersion of heat; therefore, thermal shock is hugely minimized and increases its lifespan. This property makes it especially useful in temperature-critical applications.
