Durability and Reliability with Increased Power

The 20x4mm ferrite disc is the classic, proven magnetic solution for lightweight tasks. As a ceramic magnet, it offers superior resistance to corrosion and weather elements compared to neodymium, while its increased thickness (4mm) allows it to deliver a completely stable pull force of 450 grams.

Key Features

  • Absolute Rust Immunity: Its natural chemical composition makes it 100% waterproof, allowing for permanent outdoor use without needing any protective coating.
  • Steady Pull (450g): Increased strength thanks to its thickness, ideal for safe and everyday holding tasks without the pinching risks associated with ultra-strong magnets.
  • Excellent Application: The top choice for souvenirs, fridge decorations, school builds, DIY projects, and hobbies.

Frequently Asked Questions (FAQ)

Are these magnets suitable for outdoor use?
Yes, absolutely. Unlike sensitive neodymium, ferrite magnets withstand the elements perfectly. They will not oxidize or rust, even if they are continuously exposed to rain or sun.

What weight can this magnet (20x4mm) hold?
Its pull force is estimated at 450 grams under ideal contact conditions. It is perfect for securely holding papers, cards, and menus, or for embedding into the back of small clay and wooden crafts.

Safety Note (Ceramic Material): Ferrite magnets have a ceramic structure. This makes them extremely hard but also brittle (they behave like glass or porcelain). They may chip or shatter if dropped on a hard floor or if allowed to forcefully collide with each other. Keep broken pieces away from small children.
