Beryllium S-200FC, Cold Isostatic Pressed and Sintered
Subcategory: Pure Element; Nonferrous Metal; Beryllium Alloy
Key Words: Brush Wellman; S200FC Alloys
Tensile data below for S-200FC has been supplemented with other property data generally applicable to pure beryllium.
Brush Wellman's S-200FC grade uses impact ground powder that is consolidated in a flexible rubber bag than approximates the shape of the final product. The bag is degassed, sealed, and CIP'ed. typically at 60,000 psi (414 MPa) at room temperature. The part is then sintered to 99+% density and, if required, may be hot formed to the final shape. Used for applications requiring lower property values than HIP'ed material such as optics for fire control and inertial measurements. The tooling is reusable so it is suited for making hundreds of parts.
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.
