Description

Four times lighter than steel and yet about a third stronger, beryllium is a lighter option than aluminium as a structural material in spacecraft and high-speed missiles. It counts among its more remarkable properties a low neutron absorption cross-section, which makes this metal useful as a moderator or reflector in nuclear reactors. Its ability to slow neutrons down is only comparable to its inability to stop x-rays, which is why beryllium is the material of choice for the construction of windows in x-ray tubes. However, beryllium is considered a carcinogen, which can affect people via breathing, eye contact, or broken skin contact. That's why it is advised to reduce exposure to beryllium as much as possible.

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.
