Home Products Beryllium Products Beryllium Metal BERYLLIUM METALS – HIGH STRENGTH & LOW DENSITY MATERIALS FOR ADVANCED TECHNOLOGIES Materion beryllium (Be) metals are essential for many of the most advanced technologies, providing an unmatched modulus-to-weight ratio. In addition, beryllium metals have low thermal expansion, so it is resistant to changing shape in temperature extremes. This combination of characteristics makes beryllium ideal for demanding applications, including satellites and space structures, imaging technologies and X-rays, military aircraft and telescopes. Beryllium brings unrivaled advantages to its end-use applications, including: Thermal conductivity that is better than aluminum Moderate CTE & good natural damping - reducing jitter and vibrations Low neutron absorption & high reflectivity High specific heat & high thermal conductivity Higher Modulus as the temperature decreases High infrared reflectance Low density The use of beryllium has enabled technological breakthroughs previously thought unattainable. And, beryllium is recyclable. VARIOUS SPECIALIZED BERYLLIUM METALS & APPLICATIONS Our beryllium metals come in a range of forms and chemistries: Instrument grade: I-200-H, I-70-H are hot isostatically pressed beryllium grades used in space applications and for low-density, bare polished optical applications or when reduced weight is required. These grades offer high microyield strength allowing instrumentation to keep their form when exposed to stress. Beryllium metal is more resistant to changing in temperature extremes. Nuclear grade: S-65, S-65-H are used for nuclear test reactors and fusion walls due to their neutron reflectivity, neutron kinetic energy absorption, neutron kinetic energy absorption and high purity. Optical grade: O-30-H is used in space optical applications due to the lower level scatter and ease to polish. This beryllium metal was used in the primary optics for the James Webb Space Telescope. Pure beryllium metal: UHP9999 is 99.99% pure beryllium and is used in advanced research for p-type semiconductors and high-end neutron collimators. Raw beryllium metal: B-26-D is a high purity beryllium for vacuum melting and casting. Structural grades: S-200-F, S-200-FC, S-200-FH, SR-200 are critical beryllium metals for space structures, nuclear reflectors, EO/IR systems, SWaP replacement systems, semiconductors and ISR systems.

ENGINEERING DESIGN & PROJECT SUPPORT Our beryllium metals provide higher strength-to-weight ratios than aluminum and higher resistance to heat. Engineers rely on beryllium metals for applications that are subjected to extreme temperature changes and nuclear applications that need to be neutron reflective. Our Special Products and Application Development Engineering (SPADE) team can ensure that you get optimum results when using our beryllium metals for aerospace, defense, nuclear and space applications. We help manage projects and provide engineering support from design inception to project completion, even with the most complex design challenges. Work with Materion’s SPADE group for engineering assistance on advanced applications. SAFE HANDLING OF BERYLLIUM Beryllium, its alloys, and its salts can be handled safely if certain work codes are observed, but no attempt should be made to work with beryllium before becoming familiar with proper safeguards.
