Molybdenum

Molybdenum is known for its strength and toughness, serving as a significant alloying agent to improve hardenability and toughness. Corrosion and abrasion resistance properties also make it popular for various metal fabrications. This silvery-white metal is strong even at elevated temperatures with a high melting point. Since molybdenum is not very ductile or malleable, it is often used to produce spacecraft, aircraft, missile parts and other metal components.

Why Is Molybdenum Useful in Parts Fabrication?

Molybdenum is a renowned material in the field of metal fabrication because of its strength, durability and other features. Key properties of molybdenum that make it popular in various industries include:

  • Extremely resilient with a melting point of up to 2,623°C
  • Corrosion-resistant, particularly to hydrochloric acid, glass and other metals
  • Exceptional electrical properties with low thermal expansion
  • Readily alloyed for improved capabilities and higher temperature resistance

Molybdenum is a renowned material in the field of metal fabrication.

Industries That Use Molybdenum

With its extreme durability and excellent corrosion resistance, molybdenum is widely used in different industries that require strong and adaptable components. The uses for molybdenum metal are extensive, including in the following sectors:

  • Aircraft: Several components in aircraft engines rely on sturdy metal components with molybdenum. It is a core element in the production of engine blades, suspension systems, structural parts and more.
  • Electronics: Molybdenum’s thermal properties and high thermal conductivity make it ideal for manufacturing parts for electronics, including barrier layers, electrodes and other electrical wirings.
  • LED and film technology: LEDs and other products related to film technology need metals that can withstand high temperatures. Molybdenum offers remarkable mechanical stability and durability even at high melting points.
  • Thermal spray technology: The corrosion resistance of molybdenum is ideal in thermal spray production. It works as a strengthening alloy agent to enhance durability and as a coating medium to protect from corrosion and wear.
  • Glass manufacturing: The glass manufacturing industry is another sector that benefits from the strength of molybdenum. Some of the products that use this metal are furnaces, switch electrodes and heat shields.
