High-Purity Rare Earths



For MSDS Sheets, please go to our MSDS page.

At ACI Alloys, we make high purity rare-earth metals and alloys in house.
All lanthanide metals and alloys are arc-cast in a pure argon amosphere
into cold copper crucibles. We will custom make almost any material
at whatever size and stoichiometry you request. 
(Note: We don't work with promethium, which is radioactive.)
Elements to the left of Gd in the above table are reactive in air,
and may need to be shipped in mineral oil or a dessicant to minimize oxidation.
