Bulk Powerful Neodymium Block Magnets

Neodymium block magnets are a type of rare earth magnet made from neodymium, iron, and boron. These magnets are the most vital permanent magnet type available and are used in various applications. They are often found in motors, generators, loudspeakers, hard drives, and other devices that require strong magnetic fields.

Features

Neodymium block magnets generally have a more extensive surface area than other forms. This trait makes them more appealing and allows them to achieve more significant outcomes.
Meanwhile, solid forms typically have high tensile strength. It implies they are less prone to cracking or breaking. As a result, they can be stacked or attached to other objects. They are helpful in a variety of uses.
NeoMagnets is a provider of bespoke neodymium magnets, and we can provide a variety of block forms by changing the length, breadth, and height of the blocks. Your particular application and the expected results will determine the options.

Dimensional Identifications

We commonly use some conventional techniques to determine the measurements of magnets.
The dimensions of circular neodymium magnets are listed below. You can purchase magnets from Osenc or another provider by following the steps below. It will aid in preventing confusion between the two parties.
Meanwhile, we use metric units by default for measurements, and imperial units are only for ease of comprehension. If there are slight variations, use metric measures for proof.
The dimensions of neodymium block magnets are as follows: length x width x height.
The measurement is usually preceded by the capital letter F.
If a neodymium block magnet has a size of F8 4 2 mm, it indicates it is 8 mm long, 4 mm wide, and 2 mm tall.
Magnets for blocks: Dimensions: length x width x height (For example, 10 x 10 x 10 mm)
Magnets with an opening in them: Length x Width x Height x Diameter of the Opening (For instance, 10 x 10 x 10 mm x D5 mm)
Magnetized block with a countersunk hole: Dimensions: length x width x height x primary opening dimension (For instance, 10 x 10 x 10 mm x M5 mm)
The last number is the polarization orientation of this magnet by default.
As a result, the magnetization direction is the width direction for magnetization, which is 2 millimeters.
Meanwhile, N and S are the two larger areas, representing the 8 4mm surface.
The N pole is on one side, and the S pole is on the other.

Available Dimensions

1). Available sizes for neodymium block magnets

Length: 1 – 200mm (1/16 – 7 7/8 inches)

Width: 0.5 – 100mm (1/64 – 3 15/16 inches)

Height: 0.3 – 120mm (1/64 – 4 ¾ inches)

2). The largest neodymium block magnets that we can offer

Rectangle: Length 200 × width 80 × height 50mm (7 7/8 x 3 1/8 x 1 15/16 inches)

Square: Length 100 × width 100 × height 60mm (3 15/16 x 3 15/16 x 2 3/8 inches)

The longest magnetization direction: 200mm (7 7/8 inches)

Note:

If the size of one direction is the largest, then the size of other directions should be smaller.

If the sizes of two directions are larger, the thickness should not be too small.

3). The smallest size of block magnets

Length 1 × width 1 × height 0.3mm (1/16 x 1/16 x 1/64 inches)

Grades Of Neodymium Block Magnets

The intensity of a neodymium magnet’s magnetic field determines its grade. A number denotes a neodymium magnet’s grade. A higher figure suggests a more powerful magnetic field.
Neodymium magnets come in various grades spanning from N35 to N55 and high-temperature categories for specific uses such as H, M, SH, EH, and AH.
You can learn more about neodymium magnet classes by reading our primer. It will assist you in determining which school level is best for you.

Coatings

Neodymium magnets are environmentally delicate. They can deteriorate rapidly due to dampness and other harmful factors.
To increase the longevity of neodymium magnets, we will need to cover their surfaces with a layer or levels of compounds. Meanwhile, the magnets will be more immune to scrapes and other harm due to this.
W can provide bespoke neodymium magnets with a variety of finishes. Nickel, copper, urethane, and other materials are among them. Each of them has distinct characteristics and advantages.

Magnetization Directions

The dimension designation for block magnets is typical: Length x Width x Height.
The last number of this measurement identifier represents the magnetization surface.
For example, the polarization orientation of an F20 x 15 x 10 mm magnet is a 10 mm surface.

Optional Variants

1) Magnet rods made of neodymium
Sometimes block-shaped neodymium magnets with a very long border are required. This is commonly referred to as a bar form. It has numerous uses in various goods and necessitates multiple production methods.

2) Neodymium magnets with countersunk holes
We can drill one or more openings in a single neodymium block magnet. As a result, a bolt can be inserted for securing or setting. This style is perfect for suspended signage, tools, advertising, and so on, especially for cupboards, restaurants, booths, and shops.

3) Neodymium magnet filaments, microneodymium
NeoMagnets can also provide micro magnets with minuscule measurements – typically less than 2 mm – a greater accuracy of +/- 0.005 mm, and a unique Parylene covering, frequently used in medical applications.
