Ferrite Magnet Rectangular Block 30x20x6mm
The rectangular (block) ferrite magnet measuring 30x20x6mm is a strong permanent ceramic magnet manufactured primarily from iron oxide. Delivering a steady pull force of 1.4 kilograms, it excels in its absolute resistance to rust, moisture, and extreme temperatures. Its block geometry provides geometric stability that prevents parts from rotating, making it an ideal choice for embedding into 3D prints, outdoor applications, and industrial magnetic closures. Sold individually.
Steady 1.4kg Pull and Anti-Rotation Geometry
The 30x20x6mm rectangular ferrite magnet combines the incredible durability of ceramic materials with the practical advantages of a block shape. With a 6mm thickness, it delivers a highly satisfying and reliable pull force of 1.4 kilograms, making it the premier choice for mechanisms, 3D prints, and builds where the magnetic joint must remain perfectly aligned and stable over time.
Key Features
- Absolute Rust Immunity: Thanks to its chemical composition, it never oxidizes, making it 100% suitable for permanent exposure to the outdoors, water, and moisture without any coating.
- Geometric Stability: The rectangular shape ensures that connected objects "lock" into place and do not spin on their axis.
- Strong Pull (1.4kg): The 6mm thickness enhances the magnetic field's reach, ensuring a secure hold for tools, wooden crafts, and signage.
Frequently Asked Questions (FAQ)
Which is the best magnet for 3D printing, ferrite or neodymium?
It depends on the environment. If your 3D printed object is intended for outdoor use, high moisture, or aquariums, ferrite is the ultimate choice because it will never rust. Additionally, a rectangular shape (like this 30x20x6mm block) is ideal for design integration, as its angular surface prevents lateral sliding and rotation of the parts.
Are these magnets suitable for continuous exposure to rain?
Yes, absolutely. Ferrite magnets are naturally rust-proof and weather-resistant. Unlike neodymium, they do not have a coating that can peel off, making them the ideal solution for garden signs and outdoor builds.
