5mm x 2mm Round Neodymium Disc Magnets – Ni-Cu-Ni Coated N52 | Bulk Packs

5mm x 2mm Round Neodymium Disc Magnets Stock compact, high-pull neodymium disc magnets sized 5 mm diameter × 2 mm thickness for crafts, closures, displays, and small fixture work. Each silver-finish disc uses rare-earth NdFeB material with a durable Ni-Cu-Ni (nickel-copper-nickel) coating to resist corrosion and keep a clean metallic look in daily handling. Key Features Exact 5 × 2 mm disc size: Small round profile for tight spaces, badge backs, model builds, and DIY magnet projects. Strong rare-earth pull: Neodymium (NdFeB) delivers high strength for the footprint—ideal when ferrite magnets feel too weak. Ni-Cu-Ni plated finish: Nickel-copper-nickel layering helps protect against moisture and handling wear. Silver round disc form: Stacks cleanly for packaging and installs flush on flat surfaces. Bulk pack ladder: Choose from Pack of 50 through Pack of 1000 for prototyping, resale, or production batches. How to Use Confirm polarity before bonding—disc magnets attract on opposite poles. Clean and dry both surfaces; use cyanoacrylate or two-part epoxy for permanent mounts. Keep magnets separated during storage to avoid snapping together or chipping edges. Handle with care—strong fields can pinch skin and affect sensitive electronics nearby. Best For DIY fridge magnet and craft magnet projects Light-duty closures for boxes, lids, and display fixtures Prototype magnet arrays, jigs, and workshop hold-downs Small round magnets for badges, name plates, and compact assemblies Available in graduated bulk packs so you can match order size to your job—from sample runs to full production quantities.
