Custom Magnets FAQ Summary Worth Learning

Custom magnets are magnets that are designed and manufactured according to the special needs of the customer, allowing you to better customize the magnets you need and related knowledge, the article lists some common custom magnet problems.

1、What types of custom magnets are available?

Neodymium Iron Boron Magnets: these are one of the strongest types of permanent magnets available and are typically used in applications that require a strong magnetic force.

Ferrite Magnets: lower cost and commonly used in a variety of household appliances, toys, etc.

Samarium Cobalt Magnets: with better high temperature resistance, they are suitable for applications in extreme environments.

Alnico magnets: have good temperature stability and corrosion resistance.

2、What do I need to pay attention to when customizing magnets?

Provide accurate size specifications and the required shape (round, square, shaped, etc.).

Define the required magnetic strength in order to select the appropriate material and manufacturing process.

Select the appropriate surface treatment according to the usage environment, such as nickel plating, black epoxy, etc. to enhance the corrosion resistance.

Whether the magnet needs to work in high temperature environment or exposed to high temperature.

3. Can magnets be customized to any shape?

In most cases, yes, but complex shapes may increase cost and affect magnetic behavior.

4、What is the minimum order quantity for custom magnets?

This depends on the magnet manufacturer's regulations, some manufacturers may accept a small amount of orders, while others require a larger order quantity, it is best to communicate with the manufacturer.

5、How long does it take to customize magnets?

The length of time depends on the quantity and complexity of the order and the manufacturer's production schedule. It usually ranges from a few days to a few weeks.

6、How are the tolerance ranges of custom magnets determined?

The tolerance of a magnet usually depends on the shape and application requirements. Generally, NdFeB magnets have tolerances of ±0.05mm or less, while ferrite magnets may have larger tolerance requirements.

7、What coating options are available for custom magnet surfaces?

Nickel: a common anti-corrosion coating.

Zinc: lower cost option for protection.

Epoxy: for harsh environments.

Gold: for high-end products and decorative applications.
