Description

Molybdenum CAS NO 7439-98-7 is a high-purity metallic element essential for modern industrial and technological applications due to its exceptional strength, high melting point, and excellent corrosion resistance. It serves as a critical alloying agent, significantly enhancing the hardness, toughness, and temperature stability of steels and superalloys. This makes it indispensable for manufacturers in the aerospace, defense, energy, and chemical processing industries seeking to improve product performance and durability.

Application

• Alloy Steel Production: A key additive to create high-strength, low-alloy (HSLA) steels, tool steels, and stainless steels for construction, automotive, and oil & gas pipelines.
• Superalloys for Aerospace & Turbines: Critical component in nickel-based superalloys used for jet engine parts, gas turbine blades, and other high-temperature components.
• Catalysts & Chemical Processing: Used in catalysts for petroleum refining (hydrodesulfurization) and in the production of chemicals, where its properties resist corrosive environments.
• Electrical & Electronic Components: Employed in filaments, semiconductor substrates, and as a conductive layer in thin-film transistors (TFTs) for displays.
• Industrial Lubricants & Coatings: Molybdenum disulfide (MoS₂) is a widely used solid lubricant and anti-wear additive in greases and coatings.
• Nuclear Energy & Shielding: Utilized in reactor components and shielding due to its high density and ability to withstand radiation.
• Welding & Metalworking: Used as an alloying element in welding wires and electrodes to improve weld strength and high-temperature performance.
• Specialty Chemicals & Pigments: Serves as a precursor for various molybdenum compounds used in pigments, corrosion inhibitors, and flame retardants.

Quality Control

Our Molybdenum is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and compliance with international standards. We offer various purity grades, from industrial to high-purity (99.95%+), tailored to specific application requirements. A comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical characteristics is provided with each shipment to guarantee traceability and performance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. For fine powder forms, store under an inert atmosphere such as argon or nitrogen to minimize oxidation. Maintain ambient temperature conditions (15-25°C).
