Engineers, makers, and precision fabricators working on electrical contacts, spring components, and EMI shielding need a material that combines conductivity with real mechanical strength — that's exactly where beryllium copper sheet delivers. This BeCu foil strip is sized at a versatile 200mm × 200mm (approx. 7.87\" × 7.87\") and is available in a wide thickness range from 0.08mm to 1.2mm (approx. 0.003\" to 0.047\"), letting you match the exact gauge your application requires.\u003c\/p\u003e\n\u003cp\u003eEach sheet is cut from beryllium copper alloy (C17200 \/ BeCu), a material recognized for its exceptional combination of electrical conductivity, spring-back elasticity, and corrosion resistance.
