Product Details

Product Introduction

Molybdenum bolts and nuts are high-performance fasteners manufactured through precision machining, using high-purity molybdenum or molybdenum alloys (such as Mo1, MoLa, TZM) as the primary material. These products typically feature a material purity of over 99.95% and a density no less than 10.0 g/cm³, ensuring their reliability and stability in extreme environments.

Thanks to molybdenum's high melting point of 2620°C, molybdenum bolts and nuts can maintain stable physical properties in high-temperature environments ranging from 800°C to 1700°C, allowing for long-term use without softening or deforming. They are not only heat-resistant but also possess a low thermal expansion coefficient, excellent corrosion resistance (resisting acid, alkali, and molten metal erosion), and mechanical characteristics of **high high strength and hardness.

Overview of Core Product Advantages

Advantage DimensionSpecific Description
Exceptional High-Temperature Performance

Stable physical properties at temperatures up to 1700°C, capable of

 long-term operation within the range of 800°C - 2100°C.

Excellent Thermal Stability

Low thermal expansion coefficient ensures stable preload force 

during drastic temperature fluctuations, effectively preventing

 loosening.

Robust and Durable

Manufactured from high-density rods or plates via deep processing,

 offering outstanding mechanical performance capable of

 withstanding high loads.

Wide Material Adaptability

Various options available including pure Molybdenum 

(Mo≥99.95%), Molybdenum-Lanthanum alloy (MoLa), 

and TZM alloy.

In addition to the above properties, molybdenum bolts and nuts also offer good electrical and thermal conductivity and wear resistance, enabling them to adapt to complex and demanding industrial environments industrial environments.
