Beryllium copper tools are indispensable tools in all areas in which spark-free machining is required, so Cu-Be tools are also known as non-sparking tools. Areas of application are all ATEX areas, which are operated with flammable liquids and gases, e.g.
Beryllium copper alloys are non-magnetic and have very good electrical conductivity. They have high corrosion resistance against many media. Since the non-sparking tools made of copper beryllium is also non-magnetic, it can also be used in magnetic fields.
Safety information: Copper beryllium alloys as preparations in solid form do not present a direct health hazard to humans by skin contact, inhalation and / or ingestion. However, the alloy element beryllium is very toxic. Care should therefore be taken to ensure that no inhalable particles are formed during processing, as is the case, for example, during grinding, welding and solution annealing. Machining (milling, turning, drilling) is to be regarded as safe, since no small particles can get into the air.
