Description

Misch Metal CAS NO 8006-73-3 is a pyrophoric alloy primarily composed of rare earth elements, notably cerium and lanthanum, which is critical for its powerful reducing and alloying properties. This material is essential for enhancing the mechanical and chemical performance of metals in demanding industrial applications. It is a key raw material for manufacturers in the metallurgy, automotive, and electronics sectors seeking to improve product durability and functionality.

Application

• Ferroalloy Production: A vital additive in the manufacturing of nodular cast iron and steel, where it acts as a powerful desulfurizer and deoxidizer to improve strength and ductility.
• Magnesium & Aluminum Alloys: Used as an alloying agent to enhance high-temperature strength, creep resistance, and corrosion performance in lightweight structural metals.
• Flint & Ignition Devices: The pyrophoric nature of misch metal makes it the core component for producing sparks in lighters, welding torch igniters, and military applications.
• Hydrogen Storage: Serves as a key constituent in metal hydride compounds for reversible hydrogen storage systems, crucial for clean energy technologies.
• Catalyst Precursor: Acts as a starting material for catalysts used in automotive exhaust systems and various petrochemical refining processes.
• Specialty Glass & Ceramics: Employed to modify optical properties, UV absorption, and polishing characteristics in high-performance glass and ceramic formulations.

Quality Control

Our Misch Metal is produced under strict process controls to ensure batch-to-batch consistency and meets high-purity standards for industrial applications. Quality is verified through advanced analytical techniques to confirm composition, activity, and absence of detrimental impurities. A Certificate of Analysis (COA) detailing rare earth element distribution and key specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, well-ventilated area, away from heat, sparks, and open flames. Keep container tightly sealed when not in use to prevent contact with air and moisture.
