beryllium oxide grades

Understanding Beryllium | American Machinist

Beryllium is not ductile. This contributes to its stiffness and stability and means it can be machined accurately. However, it also has characteristics that make it similar to powdered metal or sintered parts, and it fractures easily if not machined properly. Although it is relatively soft (Rc 11), beryllium is abrasive and hard on tools.
