100pcs N45 UH 3mm x 0.5mm (Approximately 1/8" x 1/64") Disc Magnets Ultra High Temperature

A versatile everyday size for magnetizing miniature parts for weapon swaps, arms, backpacks, and hatches. Plus craft clasps, hinges, and closures. The N45 UH grade holds up to heat that would weaken a standard magnet, so they're a good pick if your project sees high temperatures.

At 3mm x 0.5mm they've got a firm hold while still sitting flush in most parts. A paperclip or one of our Magnicators makes placing them easier.

N45 UH neodymium rare earth magnets, rated to around 180°C (356°F) before they start losing strength, which is over twice the ~80°C where standard N52 begins to fade. Good for anything you'd normally use Velcro, brass fasteners, hinges, or pins for, especially where heat is a factor.

WARNING: More brittle than glass, so don't let them slam together or drop them on a hard floor; they'll crack. Keep them away from anyone who might swallow them, kids or pets included, since magnets that get swallowed can pinch through the intestines and cause serious harm.
