Engineers, machinists, and precision fabricators working on spring contacts, shim stock, and RF shielding need a material that combines electrical conductivity with fatigue resistance — that's exactly where C17200 beryllium copper sheet delivers.\u003c\/p\u003e\n    \u003cp\u003eThese BeCu foil panels are cut from C17200 alloy (also known as Alloy 25), the most widely used beryllium copper grade. Available in two sheet sizes — 200mm × 200mm (~7.87\" × 7.87\") and 215mm × 200mm (~8.46\" × 7.87\") — with thickness options ranging from 0.08mm to 1.2mm (approximately 0.003\" to 0.047\"). The surface finish is smooth-rolled, and the alloy composition is nominally 98% copper with ~1.8–2.0% beryllium.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include precision spring fabrication for electronic connectors, shim stock for tight-tolerance mechanical assemblies, EMI\/RF shielding panels in enclosures, and thin diaphragm blanks for sensors and transducers.
