Whether you are a maker building RF shielding enclosures, an artist working on repousse metalwork, or a technician fabricating custom bus bars and grounding straps, these copper sheet metal panels give you a consistent, flat starting point without the waste of oversized stock.\u003c\/p\u003e\n\u003cp\u003eEach sheet is guillotine-cut from solid copper flat stock and measures 300 mm × 300 mm (approximately 11.8 in × 11.8 in). Thickness options span 0.1 mm to 0.8 mm (roughly 0.004 in to 0.031 in), covering everything from ultra-thin foil-grade shims to sturdier structural panels. The copper alloy is uncoated, giving you a bright, solderable surface straight out of the pack.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include DIY electromagnetic interference (EMI) shielding for electronics enclosures, hand-cut decorative inlays and jewellery blanks, heat-spreader patches for thermal management projects, and replacement shim stock for mechanical alignment tasks.
