Beryllium PR-200; 0.45 - 0.60 inch thick sheet

Subcategory: Pure Element; Nonferrous Metal; Beryllium Alloy

Key Words: Brush Wellman; PR200 Alloys

Material Notes:
Composition above is reported for product available from Brush Wellman. Tensile data below for this thickness PR-200 has been supplemented with other property data generally applicable to pure beryllium.

Manufactured by warm-rolling billets of vacuum hot pressed block encased in steel. Rolling creates anisotropy in the product, so cross-directional rolling techniques are often used.

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.
