Description

Cobalt CAS NO 7440-48-4 is a hard, lustrous, silver-gray transition metal with ferromagnetic properties. It is a critical raw material valued for its exceptional strength, high-temperature stability, and unique catalytic and electrochemical characteristics. This metal is essential for manufacturers in the superalloy, battery, catalyst, and pigment industries, where performance and reliability are paramount.

Application

• Superalloys & High-Temperature Alloys: A key component in nickel- and cobalt-based superalloys used for jet engine turbine blades, gas turbines, and other high-stress, high-temperature applications.
• Lithium-Ion Batteries: Used in the cathode chemistry (e.g., Lithium Cobalt Oxide - LCO) for consumer electronics, providing high energy density.
• Catalysts: Employed in petroleum refining (hydrodesulfurization), chemical synthesis (Fischer-Tropsch process), and automotive exhaust systems.
• Pigments & Dyes: Cobalt blue and other cobalt salts are used to produce vibrant, stable blue colors in glass, ceramics, paints, and plastics.
• Hard Metals & Tooling: A binder in cemented carbides (tungsten carbide-cobalt) for cutting tools, mining equipment, and wear-resistant parts.
• Magnetic Materials: Used in samarium-cobalt (SmCo) and other rare-earth permanent magnets for sensors, motors, and high-performance electronics.
• Electroplating & Surface Treatment: Provides a hard, wear-resistant, and attractive decorative finish on metal substrates.
• Animal Nutrition & Agriculture: An essential trace element (Vitamin B12) added to animal feed and fertilizers.

Quality Control

Our cobalt is produced and handled under strict quality management systems to ensure batch-to-batch consistency and traceability. We offer various grades, including high-purity (99.9%+, 99.99%+) for battery and superalloy applications, as well as standard industrial grades. Quality is verified through advanced analytical techniques, and a Certificate of Analysis (COA) detailing purity and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., argon or nitrogen) for long-term preservation of fine powders. Keep container tightly sealed when not in use to minimize exposure to air and moisture.
