Beryllium (Be) is a low-density alkaline earth metal known for its exceptional stiffness-to-weight ratio. While brittle at room temperature, its physical properties make it an ideal material for X-ray transmission and specialized use within the military and nuclear sectors.
Our high-purity Beryllium source materials are engineered for high-vacuum applications, including Molecular Beam Epitaxy (MBE) applications and semiconductor thin-film deposition via sputtering.
