Beryllium copper, also known as beryllium bronze or spring copper, is a copper alloy containing small amounts of beryllium, a rare and lightweight metal. Beryllium Copper Sheet Plate is a lightweight and lustrous metal that is produced through the electrolysis of a fused halide, such as BeCl2. This alloy is valued for its unique combination of strength, hardness, and conductivity, making it suitable for a variety of applications, particularly in industries where these properties are crucial. Beryllium copper sheets, plates, and strips are common forms in which this alloy is manufactured and used.
Composition: Beryllium copper typically contains about 0.5-3% beryllium, with the remaining composition being primarily copper. The addition of beryllium enhances the alloy's strength, hardness, and thermal conductivity while maintaining excellent electrical conductivity. This makes it an ideal choice for applications that require high performance in these areas.
