1/2" Ceramic Disc Magnet

• Grade 5 ferrite composition delivers moderate magnetic field strength at low cost
• Axially magnetized — north and south poles on disk faces for best holding/alignment
• Consistent diameter and thickness tolerances (±0.005") for precision fit in batch work
• Compatible with hot glue, epoxy, or double-sided adhesives on most surfaces
• High thermal stability up to 250°C (482°F) without demagnetization
• Brittle, hard ceramic (dark gray); suitable for indoor and most general-purpose craft/classroom use
• Bulk available in 70 or 350 count packs for classrooms, workshops, or production use

Perfect for woodworking cabinet latches, model motors, simple relays, and science lesson kits, this magnet holds papers, closes containers, fastens craft displays, and teaches hands-on magnetic concepts. Makers use it for custom fridge magnets, embedded sensor discs, and game tokens; teachers rely on bulk packs for STEM stations and magnetic discovery boards. Its high thermal resistance and low demagnetization risk make it suitable for shop environments, small electronic projects, or toy robotics—where reliable, moderate force is required.

• How strong is the magnet? Is it suitable for cabinet latches?
  It has about an 8-ounce pull—ideal for light- to moderate-duty closures in wood or craft boxes.
• Can this magnet be cut or drilled?
  No; ferrite magnets are very brittle and will shatter. Use as-is and handle with care.
• Does it lose magnetism with heat?
  No significant loss below 250°C (482°F); safe for regular indoor crafts and learning environments.
• Can this be used in water or humid environments?
  Moderate moisture is OK, but long-term use is best in dry, indoor settings. No rust, but may degrade over many years if soaked.
• What adhesive should I use to mount the magnet?
  Hot glue or epoxy are recommended for both porous and non-porous surfaces; super glue works but may weaken with repeated force.
• Are stronger magnets available for heavier projects?
  For much stronger force, consider rare-earth (neodymium) magnets; these ceramic discs are ideal for most standard craft and lesson needs.
• Is this safe for children?
  Safe for supervised handling by ages 6+; not for children under 3 due to choking hazard and brittleness.
• Does the magnet have marked poles?
  No, but north/south are on flat faces; test with a compass or another magnet to find polarity.

Choose this 1/2" Grade 5 ceramic magnet for cost-effective, moderate-strength, and reliable holding in every classroom, home, or workshop project.
