High-Purity Erbium Metal (chemical symbol: Er, CAS No.: 7440-52-0) is a premium lanthanide rare earth metal with a silvery-white appearance, available in ingot, lump, or customized sizes. Boasting a molecular weight of 167.26, density of 9.01g/cm³, melting point of 1529°C, and boiling point of 2863°C, this metal meets strict purity standards ranging from 99% (2N) to 99.99% (4N). It exhibits slow oxidation in air and water at room temperature, while being soluble in acid—properties that make it ideal for advanced industrial and scientific applications. As a trusted Erbium Metal supplier, we ensure low impurity levels, with non-rare earth contaminants like Fe, Si, and C strictly controlled to maximize performance.
Our Erbium Metal achieves 99%-99.99% purity (Er/REM), with rare earth impurities (e.g., Eu, Gd, Tb) limited to ≤0.001% and non-rare earth impurities (e.g., Fe ≤0.15%, Si ≤0.01%)—guaranteeing stable chemical and physical properties for critical uses.
With a high melting point of 1529°C and boiling point of 2863°C, High-Purity Erbium Metal retains its structure in high-temperature environments, avoiding deformation or degradation in alloy manufacturing and scientific experiments.
We offer Erbium Metal in standard ingots and lumps, as well as tailor-made sizes to fit specific customer needs (e.g., small lumps for lab tests, large ingots for industrial production), reducing material waste and processing time.
Insoluble in water but soluble in acid, Erbium Metal integrates seamlessly with other materials in alloying processes. Its slow oxidation rate also minimizes corrosion, extending the lifespan of end products like optical components.

As a key additive in special metallurgy, Erbium Metal enhances alloy properties (e.g., strength, heat resistance) for aerospace and automotive components, ensuring durability in extreme conditions.
Doped in glass, High-Purity Erbium Metal enables the production of erbium-doped fiber amplifiers (EDFAs)—critical for amplifying optical signals in long-distance fiber optic networks, supporting global telecommunications.
Erbium Metal is widely used in materials science and physics research, serving as a reference material for studying rare earth element behavior and developing new functional materials.
It imparts special optical properties to glass (e.g., high refractive index) for lasers and optical lenses, and enhances electrical/magnetic performance in erbium-doped ceramics used in electronic devices.
We offer 99% (2N), 99.9% (3N), and 99.99% (4N) purity grades, with 4N being optimal for high-precision applications like fiber optics and semiconductors.
To prevent oxidation, store Erbium Metal in vacuum-sealed packaging or under inert gas (e.g., argon) at room temperature, avoiding direct exposure to moisture or air.
Yes, we provide customized sizes (e.g., small rods, powder) based on your technical drawings or application requirements—contact our team for details.
