Engineers, electronics hobbyists, and precision fabricators who need reliable flex-fatigue resistance and consistent dimensional tolerance will find the beryllium copper sheet an indispensable material. Whether you are prototyping a contact spring, machining a shim, or cutting an EMI shield, sourcing the right thickness in a ready-to-use panel format saves hours of secondary processing.\u003c\/p\u003e\n\u003cp\u003eEach panel is cut from C17200 \/ CuBe2 alloy beryllium copper (BeCu), delivering a copper-beryllium composition that balances electrical conductivity (~22% IACS) with tensile strength typically in the 1,100–1,400 MPa range in the aged condition. Panels are available in two footprints — 200 mm × 200 mm (approx. 7.87\" × 7.87\") and 215 mm × 200 mm (approx. 8.46\" × 7.87\") — across 12 thickness options spanning 0.1 mm to 1.5 mm (0.004\" to 0.059\").\u003c\/p\u003e\n\u003cp\u003eTypical use cases include: cutting custom leaf springs and snap-action contacts for electronic assemblies; fabricating thin shim stock for precision mechanical clearance adjustment; and forming EMI\/RFI shielding enclosures where both conductivity and structural rigidity are required.
