3N Erbium Metal Ingot | Vacuum‑Melting Heavy Rare‑Earth Metal

Erbium metal is a heavy rare‑earth metal with silvery‑metallic surface. It is relatively stable in dry air at room temperature, well‑known for its unique optical‑absorption property. Our erbium metal is refined in a  high‑vacuum environment, available in multiple purity grades and machinable shapes. It is widely adopted in metallurgical modification, laser‑optical industry and high‑end alloy research fields.
