Beryllium. Description. Beryllium (Be) is a silver-white and very light metal. It has a very high melting point at 2349 °F (1287 °C). It is found in nature primarily as bertrandite, which is mined in Utah, or as beryl. The combination of its light weight and high melting point makes it valuable for making metal alloys which are used in ...Beryllium copper's physical and mechanical proper- ties differ considerably from those of other copper alloys be-cause of the nature and action of the alloying elements, principally beryllium. Varying the beryllium content from about 0.15 to 2.0 weight percent produces a variety of alloys with differing physical properties. Typical values of

Roller Milling For brittle materials a new size reduction technology become important, the high-compression roller mill,which operates with profiled rollers in the pressure range 50-500 MPa.
