INSTRUMENT GRADE BERYLLIUM FOR AEROSPACE & SPACE


Our hot isostatically pressed beryllium metals, I-220-H and I-70-H, are lightweight and infrared reflective. Combined with their high stiffness and stability over a range of temperatures, these metals are ideal for decreasing the weight of instrumentation in aircraft and satellites.

INSTRUMENT GRADE BERYLLIUM APPLICATIONS & ATTRIBUTES

I-70-H Beryllium

I-70-H grade beryllium consists of 99% beryllium with a maximum of 0.7% beryllium oxide. Low oxide grades allow for bare beryllium mirrors to yield a lower level scatter and to polish easier than higher oxide grades. I-70-H grade beryllium metal is stable over a wide range of temperatures from -196°C to 226°C (-321°F to 440°F) and offers superior reflectivity in the far infrared region (98.5% at 8-12 micron wavelengths) without optical coatings. This IR reflectivity enables designers to create defense applications that are more difficult to detect.

I-70-H is available in several forms, including rod, bar cut from block and specialty sizes or shapes.

I-220-H Beryllium

I-220-H beryllium is an instrument grade beryllium metal used in applications requiring high resistance to plastic deformation at low stress levels. The high resistance to plastic deformation at low stress levels is crucial for applications that require high micro-yield strength. Typical uses include telescope supports on space exploration satellites and optical satellites.

I-220-H is available in several forms: rod, bar cut from a block and specialty sizes or shapes.
