Tensile data below for S-200FH has been supplemented with other property data generally applicable to pure beryllium. Brush Wellman's S-200FH grade uses impact ground powder that is consolidated in a sheet metal can formed into the shape of the final product. The can is degassed, sealed, and HIP'ed. typically at 1000°C and 15,000 psi (103 MPa). This results in a denser, more isotropic product with better mechanical properties than traditional vacuum hot pressed material. 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.
