Description

Neodymium is a soft, silvery-white rare earth metal with the atomic number 60. It is a critical component in the production of the world's strongest permanent magnets, known as NdFeB magnets, which are essential for modern high-performance technologies. This metal is indispensable for manufacturers in the electronics, automotive, and renewable energy sectors, where its unique magnetic properties enable miniaturization and efficiency. Neodymium CAS NO 7440-00-8 is supplied in various forms, including ingots, powder, and foil, to meet diverse industrial processing requirements.

Application

• Permanent Magnets: The primary application is in Neodymium-Iron-Boron (NdFeB) magnets for electric vehicle motors, wind turbine generators, hard disk drives, and high-performance speakers.
• Specialty Alloys: Used as an additive to magnesium and aluminum alloys to enhance high-temperature strength and creep resistance.
• Glass & Ceramics: Acts as a coloring and decolorizing agent, producing shades from pure violet to wine red and gray, and is used in protective goggles for glass blowers.
• Catalysts: Employed in polymerization catalysts and for automotive catalytic converters to reduce emissions.
• Lasers: A key dopant in yttrium aluminum garnet (Nd:YAG) and glass (Nd:Glass) lasers used in medicine, manufacturing, and ranging.
• Fluorescence: Used in phosphors for television tubes, LEDs, and other displays.
• Research & Development: Serves as a starting material for various chemical syntheses and advanced material research in academia and industry.

Quality Control

Our neodymium metal is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity levels suitable for demanding applications like magnet manufacturing. We provide comprehensive Certificates of Analysis (COA) detailing purity, trace metal impurities, and physical specifications. Our quality systems are designed to meet the exacting standards of the electronics and automotive supply chains, with traceability maintained throughout the production process.

Storage

Preserve in a tightly closed container, protected from light. Due to its pyrophoric nature in powder form and tendency to be easily oxidized (store under inert atmosphere), neodymium must be stored under an inert gas such as argon in a cool, dry, well-ventilated area away from incompatible materials like strong acids and oxidizing agents. For long-term storage of bulk material, maintaining a controlled, moisture-free environment is critical to prevent surface oxidation and degradation of magnetic properties.
