Magnet Rectangular 40x20x10mm
The rectangular (block) ferrite magnet measuring 40x20x10mm is a heavy-duty permanent ceramic magnet manufactured primarily from iron oxide. Delivering a strong pull force of 2.5 kilograms, it excels in its absolute resistance to rust, moisture, and extreme temperatures. Its robust rectangular geometry makes it the premier choice for industrial applications, magnetic separators, heavy DIY builds, and permanent outdoor use. Sold individually.
Industrial 2.5kg Strength with Absolute Geometric Stability
The 40x20x10mm rectangular ferrite magnet provides an exceptionally robust magnetic solution for demanding applications. Thanks to its large surface area and substantial 10mm thickness, it combines the incredible durability of ceramic materials with a very strong pull force of 2.5 kilograms, ensuring that the magnetic joint will remain stable and perfectly aligned.
Key Features
- Absolute Rust Immunity: As a ceramic material, it never oxidizes, making it 100% suitable for permanent exposure to rain, soil, and marine environments without any protective coating.
- Geometric Stability: Its rectangular (block) shape "locks" objects into place, preventing lateral sliding and unwanted rotation on their axis.
- Heavy-Duty Pull (2.5kg): The 10mm thickness allows the magnetic field to penetrate deeper, offering a secure hold for heavy tools, thick signage, and industrial components.
Frequently Asked Questions (FAQ)
Why should I choose this ferrite magnet over a neodymium one of the same size?
If your application is outdoors, on a construction site, or in an environment with high temperatures and moisture, neodymium will corrode and lose its properties. This ferrite magnet will endure forever in these conditions while still delivering more than enough force (2.5kg) for most heavy builds.
Can I use these magnets in 3D prints?
Yes, they are excellent for large 3D printed parts, such as tool holders or magnetic shelves. Because they are rectangular, they integrate easily into the design and offer excellent directionality and stability.
