What Are The Uses Of Molybdenum Rod?

Molybdenum rod maintains zero deformation at 2200°C and is an invisible pillar in the aerospace, military, nuclear, and semiconductor industries. FOTMA utilizes TZM alloys and precision machining technology to create core components that withstand extreme operating conditions. Molybdenum rods are widely used in the following core industries due to their high melting point, high-temperature stability, and excellent mechanical properties:
 

I. Core Industrial Applications of Molybdenum Rods

Aerospace and Military

Rocket Nozzle Throat Liners: Maintain zero deformation under 2200°C gas flow, ensuring propulsion system stability.

Hypersonic Vehicle Leading Edge Components: Withstand 1648°C high-speed airflow and maintain structural rigidity.

Vacuum and High-Temperature Equipment

Vacuum Furnace Heating Elements and Supports: Leveraging a melting point of 2623°C, they achieve uniform heating and high-temperature structural stability.

Sapphire Crystal Growth Furnace Support Components: Temperature control accuracy reaches ±1°C, increasing crystal transmittance to 99.8%.

Energy Sector

Nuclear Reactor Neutron Absorber Plates: Radiation-Resistant to Creep at 2000°C, Deformation <0.1%.

Photovoltaic Glass Melting Furnace Stirring Rods: Liquid-Resistant to Corrosion at 1350°C, Annual Loss <3%.

Electronics Industry

Semiconductor Manufacturing Electrodes: Impurity Emission Rate <0.001ppm at 1800°C, Ensuring Chip Purity.

Precision Electronic Device Frames: Extremely Low Thermal Expansion Coefficient, Ensuring High-Precision Equipment Stability.

II. FOTMA Molybdenum Rod Technology Advantages

Material Properties

High-Temperature Resistant: TZM molybdenum alloy screws achieve a flexural strength of 930 MPa at 2200°C, 52% higher than ordinary molybdenum rods.

Creep Resistance: Deformation <0.005mm after 1000 hours of continuous load at 1800°C.

Precision Machining

Nanoscale Precision: Straightness ≤ 0.01mm/m, threads reaching ISO 4H grade. Ultra-smooth surface finish: Polished to Ra ≤ 0.4μm, meeting semiconductor-grade cleanliness standards (outgassing rate <10⁻⁹ Pa·m³/s).

Application Adaptability

Full Customization: Covering sizes from M1.2 micro screws to Φ200mm large components, with 72-hour emergency delivery.

Multi-Form Supply: In addition to standard rods, we also offer special-shaped connectors such as molybdenum screws and nuts.

III. Typical Case Studies

Aerospace: TZM molybdenum rods have survived 100 hot and cold cycles at 2200°C without cracking, certified for use in rocket engines.

Industrial High-Temperature Equipment: Used in multi-layer heat shields for vacuum furnaces, they reflect 90% of heat radiation and reduce energy consumption by over 30%.

Molybdenum rods are the “invisible pillar” of high-temperature, high-precision industrial applications. Through innovative materials (such as TZM alloys) and precision machining technologies, FOTMA provides core components that withstand extreme operating conditions for the aerospace, nuclear energy, semiconductor, and other industries.
