Beryllium copper reed, beryllium copper finger shrapnel material, beryllium copper (BeCu) is a high-performance metal

Beryllium copper reed, beryllium copper finger shrapnel material
Beryllium copper (BeCu) is a high-performance metal that can be cast and used in a wide range of parts applications. Its mechanical and electrical properties make it reasonable
Think of electromagnetic interference and radio frequency interference shielding product materials.
The electrical properties of beryllium copper provide shielding over a very wide frequency range, while its mechanical properties have a high deviation range and long life without compression, beryllium copper shrapnel provides maximum elasticity and fatigue resistance, and has excellent electrical conductivity with a variety of coating options. Beryllium copper has a high life cycle and conforms to large gap differences, making it the best material for attenuation.
