I. Magnet material.SourceRare earth magnet-

There are several types of magnetic materials, and depending on the value you want to get out of your product or how you want to use it will determine which material you need to customize your magnet.SourceRare earth magnet-

1.Neodymium iron boron (NdFeB): NdFeB is divided into sintered NdFeB and bonded NdFeB, the most widely used in the market is sintered NdFeB. Neodymium magnets also have many uses, such as neodymium tile magnets, neodymium ring magnets and neodymium cylindrical magnets, especially for making motor magnets.SourceRare earth magnet-

2.SmCo: SmCo magnets are relatively high value, high temperature resistant, corrosion resistant, generally without plating treatment, SmCo magnets important characteristic is high temperature resistance.SourceRare earth magnet-

AlNiCo: AlNiCo magnets have low coercivity, easy to demagnetize if not handled carefully, and are hard and brittle. They are best suited for high temperature applications.SourceRare earth magnet-

Ferrite/Ceramic materials: Ferrite materials can be used in a variety of electronic devices. This is due to their hard, brittle and polycrystalline nature and are characterized by being inexpensive and have been processed. The disadvantages are weak magnetism and large size.SourceRare earth magnet-

II. ShapeSourceRare earth magnet-

Magnets come in many shapes and these shapes determine how the magnets are used. The shape of each magnet determines the strength of its pull and how the magnetic field lines are arranged on the outside of the magnet. The following are some common choices of magnet shapes.SourceRare earth magnet-

1. Square magnets: Square magnets are usually straight-sided with six sides and all angles are right angles (90°). These types of magnets are primarily used for fixturing applications where they are mounted in channels to help increase their holding power. When using square magnets for customization, you will need to provide data on the length, width and height of the magnet.SourceRare earth magnet-

2. Round magnets: Round magnets are thin, flat, circular magnets whose thickness does not exceed their diameter. They are the most versatile and commonly used magnet shape. Disc magnets are widely used for holding applications. As with block magnets, you must also provide data on the length and diameter of the magnet.SourceRare earth magnet-

3. Arc magnets: Arc magnets are often used in special cases such as electric motors, generators and alternators, especially for rotors and stators. Again, you will need to provide specifications for the outside diameter, inside diameter, length and angle of the magnets.SourceRare earth magnet-

4. Ring magnets: Ring magnets have several interesting applications, such as demonstrating magnetic repulsion in scientific experiments and sometimes in medicine. Depending on the purpose of the customization, you will need to provide the correct information on the outside diameter, inside diameter and length of the magnet.SourceRare earth magnet-

III. GradesSourceRare earth magnet-

Different magnet materials are available in different grades. Ideally, the grade of a magnet is a good measure of its strength. Typically, higher grade numbers indicate a stronger magnet. This means that if your project requires a strong magnet, you should choose a magnet with a higher number (grade).SourceRare earth magnet-

1. Neodymium magnets: Grades are usually from N25 to N55.SourceRare earth magnet-

2. Samarium Cobalt magnets: common grades from 16 to 32.SourceRare earth magnet-

3. Alnico magnets: common grades from 1 to 9.SourceRare earth magnet-

4. Ferrite/Ceramic Magnets: Common grades from 8 to 40.SourceRare earth magnet-

IV. Magnetization Direction.SourceRare earth magnet-

When it comes to magnetization direction of magnets, there are two main types. You can use either radial or axial (radial) magnetization magnets. Radial magnetization is created in specially manufactured ring magnets. When the magnetization direction of the magnet is on the axis of the magnet, it is called axial magnetization.SourceRare earth magnet-

The direction of magnetization is important when making magnets because a magnet will usually attract the most when one of its poles touches the magnetic surface to which you want it to adhere. Thus, for example, an axially magnetized magnet is most effective when one of the planes touches the surface.SourceRare earth magnet-

V. Tolerances.SourceRare earth magnet-

Tolerances are actually parameters used in the manufacture of mechanical components and are usually measured according to a standardized system of tolerances called international tolerance classes. Usually, the tolerance of a magnet is measured in +/-0.05 mm, just like in neodymium magnets. However, the exact tolerance measurement depends largely on the shape, grade and material of the magnet, and the smaller the tolerance, the more difficult and costly it is relative to machining.SourceRare earth magnet-

Common plating of magnets.SourceRare earth magnet-

VI. Plating.SourceRare earth magnet-

The choice of magnet plating is determined by the actual magnet application environment. Many different coatings can be used, such as nickel-copper-nickel coating, zinc coating, epoxy resin coating, gold coating, etc. For neodymium magnets, polytetrafluoroethylene (PTFE) and oak are good choices for coating materials.SourceRare earth magnet-

VII. Customized quantity.SourceRare earth magnet-

Finally, the amount of material needed to make a custom magnet is another important factor to consider. To get a quote for a custom magnet, you will need to provide the quantity required. Generally speaking, the higher the quantity of magnet material required, the lower the unit price of the custom magnet.SourceRare earth magnet-
