This rare earth metal is soft and silver-white with a moderate melting point. Pure samarium exhibits a very rich set of magnetic properties at different temperatures, and its cobalt alloys are used to manufacture high temperature magnets. It has a high thermal-neutron cross section, which means that it is capable of absorbing neutrons efficiently, making it suitable for its use in nuclear reactor control rods. Similar properties also make this metal useful in CRT TV screens and in IR-absorbing glasses.

This material data has been provided by Matmatch.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
