BRUSH WELLMAN I-220 is an instrument grade of beryllium strengthened by a dispersion of 2.2% beryllium oxide maximum. It has a micro-yield strength of 5000 psi minimum. I-220B is manufactured from impact ground powder and therefore is more isotropic than BRUSH WELLMAN S-200E. I-220 is often used as an optical support bench because of its high degree of isotropy and good micro-yield strength. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Be-7. Producer or source: Brush Wellman Inc..

BRUSH WELLMAN SR-200E is a grade of beryllium strengthened by a dispersion of beryllium oxide (2.0%). It has relatively high strength and ductility (a minimum of 10% elongation). Its uses include missiles, space vehicles, structural parts on both commercial and military satellites and optical support benches. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Be-5. Producer or source: Brush Wellman Inc..

BRUSH WELLMAN Alloy 360 beryllium nickel strip combines unique mechanical and physical properties required in electrical, electronic and electromechanical systems. Strength, stress-relaxation and fatigue are some of those properties. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and surface treatment. Filing Code: Ni-413. Producer or source: Brush Wellman Inc..

BRUSH Alloy 25 attains the highest strength and hardness of any copper-base alloy. In the age-hardened condition, its tensile strength can exceed 200,000 psi and its Rockwell C hardness can reach 45. Its many applications include springs, deep-drawing parts, current-carrying springs connectors. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cu-356. Producer or source: Brush Wellman Inc..
