ANSWER
In machining Beryllium (Be) and its alloys, the fine Beryllium dust generated while cutting the material can be dangerous to health. It is essential to use machine tools equipped with appropriate chip collecting units.
Due to Beryllium’s high brittleness, the machined surface may be damaged during machining by microcracks and microflow. To avoid surface damage, the machining process should be under control - rigid workpiece clamping and eliminating vibrations are extremely important.
Beryllium bronze, which is also known as beryllium copper or BeCu, has good machinability. When machining this alloy, users should follow ISCAR's recommendations regarding the cutting data that relates to copper alloys.
