Aerospace Field

According to the ASTM B196-1990 (1992, 1993 editions) standard, the chemical composition and process control of beryllium copper endow this alloy with outstanding mechanical properties and excellent processing quality. As a precipitation-hardening alloy with a copper matrix and specified strengthening elements, C17300 beryllium copper exhibits excellent ductility and cutting performance during cold processing, and performs well in hot processing as well. Its main applications include key components such as diaphragms, diaphragm boxes, bellows, and springs, providing reliable material support for aerospace, electronic equipment, precision instruments, and high-end mechanical manufacturing fields.

The application of C17300 beryllium copper in aerospace and electronic equipment is also becoming increasingly widespread. The combination of high strength and high thermal conductivity enables this alloy not only to withstand repeated impacts under extreme conditions, but also to dissipate heat quickly, ensuring the stable operation of electronic components. Its non-magnetic nature and excellent corrosion resistance make it an indispensable material choice in marine engineering and precision instruments.

The difference in shielding effectiveness of different thicknesses of beryllium copper alloys

Researchers also conducted tests on beryllium copper alloy shielding materials of different thicknesses. The results showed that when the thickness of the beryllium copper alloy shielding layer increased from 1mm to 3mm, in the same magnetic field environment, the shielding effectiveness increased by approximately 10dB. In some aerospace equipment with extremely high shielding requirements, such as highly sensitive space detectors, thicker beryllium copper alloy shielding structures are adopted to further enhance the magnetic field shielding ability, ensuring that the electronic components inside the detector can still work stably in extremely complex magnetic environments and accurately collect and transmit scientific data.

In the field of unmanned aerial vehicles (UAVs), the shielding effectiveness of beryllium copper alloy-made shielding covers is also remarkable. Relevant tests show that in complex electromagnetic environments, UAVs equipped with beryllium copper alloy shielding covers have significantly reduced interference to their communication and flight control systems. The bit error rate of signal transmission has dropped from 10% to below 1%, effectively ensuring the stability and reliability of the UAV during mission execution. In military reconnaissance UAVs, stable communication and flight control are key to completing reconnaissance tasks. The shielding effectiveness of beryllium copper ensures that UAVs can accurately receive and execute instructions in the complex electromagnetic interference environment of the enemy, successfully completing reconnaissance tasks.

In the electronic equipment compartments of satellites, beryllium copper alloys are widely used as shielding materials. Through in-orbit monitoring data, it was found that after using beryllium copper alloy shielding, the magnetic field intensity inside the electronic equipment compartment remained at an extremely low level. The failure rate of the equipment was reduced by more than 50% compared to when no shielding measures were taken, significantly improving the reliability and service life of the satellite. For example, a remote sensing satellite, after being launched into orbit and operating for many years, its onboard electronic equipment, due to the effective protection of beryllium copper alloy shielding, still maintained a good working condition and continuously provided high-quality remote sensing image data to the ground.
