EMI / RFI Beryllium Copper
RFI / EMI Shielding Products are designed to either keep out or keep in electromagnetic interference. Shielding reflects and absorbs incident radiation waves. Although many applications require both environmental and EMI/RFI shielding, many do not, and are reliably shielded with BeCu contact strips.
Beryllium Copper (BeCu) is a high performance metal which can be fabricated into a wide variety of components. Its mechanical and electrical properties make it the ideal material for RFI/EMI shielding products. Beryllium copper’s electrical properties provide shielding effectiveness over an extremely broad frequency range. At the same time, its mechanical properties yield a high deflection range, in addition to a long life without compression set.
BeCu alloy 25 (CA172) is used in these applications for maximum spring properties of strength and fatigue resistance.
Custom Designed Shielding
Fralock supplies many custom designed beryllium copper and stainless steel shielding components for special applications from high volume requirements using progressive dies, to prototype and small quantities utilizing photoetch fabrication.
