Home Products Beryllium Products Beryllium Metal S-200-F C S-200-F C GRADE BERYLLIUM S-200-F C grade beryllium is a cold isostatically pressed, sintered grade of beryllium consisting of a minimum of 98.5% beryllium. While the tensile properties are lower than other grades of beryllium, the modulus, and thermal properties are the same. S-200-F C is commonly used for nickel plated optics and structures that require stiffness. S-200-F C is commonly certified to the Materion specification S-200-F C. It can also be certified to the industry specification AMS7910 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 38.0 (262 MPa) Yield Strength (0.2% offset), ksi, min 25.0 (173 MPa) Elongation (% in 4 diameters), min 2.0 AVAILABLE DESIGN CONFIGURATIONS Available in special shapes based on the part shape.
