Ceramic Ferrite Ring Magnet Burnur Grade 12 Heavy Duty 3.54″ OD

Description

Product Overview

The Burnur Ceramic Ferrite Ring Magnet is engineered from high‑grade hard ferrite material, delivering a stable magnetic field that meets Grade 12 specifications. With an outer diameter of 3.54 inches, an inner diameter of 2.36 inches, and a thickness of 0.5 inches, the ring shape provides through‑thickness magnetization, ensuring maximum holding force across the entire surface. The magnet’s BrMax rating of 3850 gauss translates to a powerful pull that can securely attach to metal surfaces, hold heavy objects, and maintain position in demanding environments.

Manufactured by Burnur, a trusted name in industrial magnets, this product is designed for durability. The ceramic composition is inherently resistant to rust, corrosion, and demagnetization, allowing it to perform reliably in both fresh and salt water settings. Its non‑magnetic housing eliminates interference with nearby electronic equipment, making it suitable for scientific labs, hobbyist workshops, and production lines alike.

Key specifications include a weight of 7.83 ounces, a model number of 90x60x13, and compliance with strict quality standards. The magnet has earned a solid customer rating of 4.3 out of 5 stars from 31 reviews, reflecting consistent performance and satisfaction among users.

Usage

Designed for versatility, this ring magnet excels in a variety of applications. In educational settings, it serves as a reliable component for physics experiments, magnetic field demonstrations, and hands‑on learning kits. Hobbyists appreciate its strength for crafting projects such as custom refrigerator magnets, magnetic jewelry, and DIY magnetic closures.

Industrial users benefit from its heavy‑duty capabilities on production lines, where it can be employed to hold metal parts in place during assembly, act as a magnetic separator for ferrous contaminants, or function as a component in magnetic couplings and sensors. Its resistance to moisture makes it ideal for marine environments, aquarium setups, and outdoor installations where exposure to water and humidity is common.

Because the magnet does not contain neodymium, it offers a safer alternative for users concerned about brittleness or toxicity. The ring shape also provides a convenient way to mount the magnet onto shafts, rods, or other cylindrical objects without the need for additional fixtures.

FAQ

What is the difference between a ceramic ferrite magnet and a neodymium magnet?

Ceramic ferrite magnets, like this Burnur ring, are made from iron oxide mixed with strontium or barium carbonate. They are less brittle, more resistant to corrosion, and generally safer to handle than neodymium magnets, which are stronger but can chip or break more easily.

Can this magnet be used in salt water without losing strength?

Yes. The ferrite material is inherently non‑reactive to both fresh and salt water, so the magnet retains its full magnetic force even after prolonged exposure to marine conditions.

How much weight can this magnet hold?

While the exact holding capacity depends on the surface material and orientation, the Grade 12 rating and 3850 gauss BrMax typically allow the magnet to hold several pounds on flat steel surfaces.

Is the magnet safe for use around electronic devices?

The magnet’s field is confined to its ring shape and does not emit stray fields that would interfere with most electronic equipment. However, it should still be kept at a reasonable distance from sensitive magnetic storage media.

What should I do if the magnet arrives damaged?

Contact Burnur customer support within 30 days of receipt. Provide photos of the damage and your order details, and we will arrange a replacement or refund according to our warranty policy.
