Beryllium, Beryllium Alloys, and Beryllium Composities

Beryllium, Be, is the only light metal having a high melting point. The majority of commercially produced beryllium is used in alloys, principally copper–beryllium alloys. The usage of unalloyed beryllium is based on its nuclear and thermal properties and its uniquely high specific stiffness, ie, elastic modulus/density values.

Managing Health Effects of Beryllium Exposure.

Few studies have investigated beryllium-metal alloys. Benson et al. (2000) performed biodistribution studies in C3H/HeJ mice given particles of beryllium-metal or beryllium-copper alloy (2% beryllium and 98% copper) intratracheally. The alloy was given at 12.5, 25, or 100 µg, and beryllium metal was given at 2 or 8 µg.

About Beryllium

Beryllium-copper (BeCu) alloys usually contain about 2 percent beryllium, but vary greatly in composition to meet different industrial and consumer needs. Beryllium contributes hardness, strength, high electrical and thermal conductivity, and resistance to corrosion, wear, and fatigue. For example, BeCu springs "bounce back" to their original ...
