Material Notes:
Mechanical property values below are in the longitudinal direction; transverse values generally lower. This is a powder metallurgical product produced by gas atomization available as rod, bar, tube and sheet. These shapes are derived by consolidating the Al/Be powder by hot isostatic pressing (HIP) and cold isostatic pressing (CIP) followed by extrusion. The extruded bar is fabricated by CIP'ing the isotropic spherical Al/Be powder into semi-dense billets and then canning the billet for subsequent extrusion with a minimum of 4:1 reduction ratio.Used for heat sinks and structural parts in aircraft and satellite avionics because of its low density, high modulus, high thermal conductivity, low CTE, thermal stability and isotropic properties.Health hazards are associated with beryllium, especially when present as airborne particles generated during processing. Be aware of hazards and take steps to reduce exposure to a safe level.Brush Engineered Materials Inc. changed its name to Materion Corporation in March 2011.
