Beryllium O-30-L, Optical Grade
Categories: Metal; Nonferrous Metal; Beryllium Alloy; Pure Element

Material Notes: Property data below for HIP'ed O-30L has been supplemented with other property data generally applicable to pure beryllium.

The powder for this optical grade of Be is produced by gas atomization (spherical powder). This results in isotropic properties. HIP'ed O-30 has a typical microyield strength (stress required to produce one microinch of permanent strain) of 4.5 - 5.2 ksi (31.0 - 35.9 MPa).

Please note that there are health hazards associated with beryllium, especially when present as airborne particles generated during processing. As with any material, be aware of hazards and take steps to reduce exposure to a safe level.

General beryllium information: Beryllium is one of the lightest metals and has a high strength-to-weight ratio, stiffness-to-weight ratio, and very high specific heat, thermal conductivity, and heat of fusion. It has significant ductility, is readily machined and can be rolled, drawn, or extruded. It finds applications in nuclear reactors (neutron moderator and reflector), X-ray sources/detectors (X-ray transparency), IR target acquisition systems, inertial guidance instruments, computer parts, other aircraft and satellite structures, and heat sink constraining cores. Beryllium is usually produced via a powder metallurgy process to improve machinability and mechanical properties.
