Home Products Beryllium Products Beryllium Metal SR-200 SR-200 GRADE BERYLLIUM SR-200 grade beryllium is a sheet product manufactured by warm rolling billets of vacuum hot-pressed block. It is often selected by designers seeking high-performance heat sinks and structural supports in military electronic and avionics systems and is well-suited for satellite structures as a hot-formed material. SR-200 is commonly certified to the Materion specification SR-200. It can also be certified to the industry specification AMS7902 prepared by SAE Aerospace. TENSILE PROPERTIES Minimum tensile properties for the material at room temperature (testing compliant to ASTM E-8) Ultimate Tensile Strength, ksi, min 70.0 (483 MPa) Yield Strength (0.2% offset), ksi, min 50.0 (345 MPa) Elongation (% in 4 diameters), min 10.0 AVAILABLE DESIGN CONFIGURATIONS Available in made to order thickness ranging from 0.020" to 0.250" (0.5 mm to 6.25 mm) with maximum dimensions of 24" x 72".
