Jun 25, 2019· Beryllium is extracted from two types of ores; beryl (Be 3 Al 2 (SiO 3) 6) and bertrandite (Be 4 Si 2 O 7 (OH) 2). While Beryl generally has a higher beryllium content (three to five percent by weight), it is more difficult to refine than bertrandite, which on average contains less than 1.5 percent beryllium.
Beryllium Copper Overview. Copper beryllium alloys are used for their high strength and good electrical and thermal conductivities. There are two groups of copper beryllium alloys, high strength alloys and high conductivity alloys. The wrought high strength alloys contain 1.6 to 2.0% beryllium and approximately 0.3% cobalt.
