Customer case story: CERN
BUMAX provides premium hexagon fasteners to the CERN Particle Accelerator in Switzerland. The BUMAX® 109 high-strength fasteners used are capable of withstanding both extreme heat and near absolute zero temperatures.
BUMAX® 109 is used for all the fasteners at CERN, and 130,000 pieces are supplied each year on average. BUMAX® 109 fasteners withstand cryogenic temperatures of 1.9 Kelvin (minus 271°C) and also retain their properties during bake-out temperatures of up to 300°C. Importantly, the non-magnetic nature of the fasteners ensures that they do not interfere with the movement of particles and magnetic field in the accelerator.
