Neodymium Ring Magnet - OD12.7mm x ID3.12mmx H4mm

This Neodymium Ring Magnet measures 12.7mm outer diameter x 3.12mm inner diameter x 4mm height and delivers exceptional magnetic strength in a compact ring design. Manufactured from premium Neodymium (NdFeB) Rare Earth material, this magnet provides far greater holding power than standard ferrite rings of similar size. With its central bore, it is easily integrated into mechanical assemblies, electronics, and fastening systems. A durable Nickel-Copper-Nickel (NiCuNi) coating protects against corrosion and wear, ensuring long-lasting performance.
