Product description

The rare earth magnet is a very different magnet from the other magnets. Its source is known to be the periodic table, with 17 elements being counted as its part.

Besides, these magnets are known to be used in hi-tech companies, contrary to the other common magnets. Also, they are known to be used when a great magnetic pull is needed. There are mostly used in technology, manufacturing as well as engineering companies.

Custom Rare Earth Magnets

Our company has experts who specialize in making these quality magnets. The magnets are manufactured in different sizes based on the role they are supposed to play.

Also, these magnets are manufactured in different shapes; they can be cylindrical, rectangular, or circular. Besides, they can be manufactured in different colors based on the customer’s needs and the particular magnet’s work.

Magnet Plating and Coating Options

The Above Chart is a list and description of common plating options for custom magnets. Why do magnets need to be plated?

❃ Oxidization (Rust)
Nd-Fe-B magnets will oxidize(rust) if left exposed in air. When a plating wears down or cracks, the exposed area will oxidize. An oxidized area will not result in complete degradation of the magnet, only the oxidized area will lose its strength. However the magnet will lose some structural integrity and become more susceptible to breakage.

❃ Durability
Depending on shape, permanent magnet substrate is brittle. A multilayered metal plating like nickel or zinc improves the magnets resistance to chipping and wear, particularly around corners.

❃ Harsh Environments
Plating vary in their tolerance of different harsh chemicals and abrasion. Salt and humidity in regions near the ocean are commonly overlooked when selecting a plating. Be sure to consider the magnets environment when selecting a plating. The most common type of plating for neodymium magnets Nickel (Ni-Cu-Ni) Intended for indoor use. It has proven to be very resilient when subjected to normal wear and tear. However it will corrode outdoors in prolonged exposure to salt water, salty air, or harsh chemicals.

Magnet Application Fields

Rare earth magnets refer to the strongest magnets ever known with high-quality performance compared to other ceramic and alnico magnets. Comprehending rare earth magnets involves understanding what they are made of and their origin.

Therefore, the 17 elements of the periodic table are part of the rare earth family, with fifteen being termed as lanthanides and the other two being the scandium and the yttrium.

Common Applications are holding systems requiring very high holding forces, sensors, reed switches, hard disc drives, audio equipment, acoustic pick-ups, headphones & loudspeakers, MRI scanners, magnetically coupled pumps · motors & generators, magnetic tool holders, magnetic bearings, door catches, dental instruments, medical devices, magnetic separators, lifting machinery, crafts & model making, hanging artwork, levitation devices, POP displays, commercial signage, packaging closures, jewelry clasps & more.
