With their silver color and compact size, these magnets are perfect for use in a variety of projects, including DIY crafts, home improvement, and industrial applications. Their strength and durability make them ideal for use in holding, attaching, and securing items.


FAQs of 40 x 20 x 10mm Neodymium Block Magnets:


Q: What is the size of these magnets?

A: These magnets are 40 x 20 x 10mm in size.

Q: What type of magnet are these?

A: These magnets are NdFeB magnets, which are a type of permanent magnet.

Q: What color are these magnets?

A: These magnets are silver in color.

Q: What can these magnets be used for?

A: These magnets can be used for a wide range of applications, including holding, attaching, and securing items in DIY crafts, home improvement, and industrial projects.

Q: Are these magnets strong?

A: Yes, these magnets are made from NdFeB magnet material, which is known for its strength and durability.


Remarkable Strength and Durability

Engineered with premium-grade NdFeB, this block magnet demonstrates very high tensile strength and a high pull force, making it the preferred choice for demanding environments. Its Ni-Cu-Ni triple-layer coating delivers outstanding corrosion resistance, extending its operational life beyond 10 years when used under moderate conditions.


Versatility for Multiple Applications

The compact 40 x 20 x 10 mm size and sharp, machined edges ensure precise installation and reliable grip. Widely utilized in industries, electronics, magnetic separation, experimentation, and DIY projects, its high flux density and permanent magnetism make it adaptable for any task that demands powerful magnetic holding.

FAQ's of 40 x 20 x 10mm Neodymium Block Magnets:


Q: How is the magnetization direction configured in these Neodymium block magnets?

A: These magnets are magnetized through the thickness (10 mm), meaning the north and south poles are aligned along the shortest dimension, ensuring optimal holding strength for surfaces positioned perpendicular to this axis.

Q: What benefits does the Ni-Cu-Ni coating provide to the magnet?

A: The Nickel-Copper-Nickel coating offers superior corrosion resistance, shielding the NdFeB material from moisture and oxidation. This triple-layer finish also enhances the magnet's durability, making it suitable for long-term use in various environments.

Q: When can these magnets be safely used in terms of temperature?

A: These block magnets can operate safely up to a maximum temperature of 80C. Exceeding this limit may cause irreversible loss in magnet strength, so they're best used in moderate temperature conditions.

Q: Where are these magnets commonly applied?

A: They are widely utilized in industrial settings, electronic assemblies, magnetic separation processes, scientific experimentation, and DIY projects, wherever a high-strength rare earth magnet is required.

Q: What is the process for ordering custom sizes?

A: Custom sizes are available upon request to suit specific applications. To place an order, contact us with your required dimensions, and we will provide tailored solutions subject to minimum order quantities.

Q: How does the magnet's sharp, machined edge affect its usage?

A: The sharp, machined edge ensures a precise and stable fit during installation, improving the holding capacity in assemblies where accuracy and tight tolerances are critical.

Q: What is the key advantage of using these magnets in magnetic holding applications?

A: Their high flux density, robust tensile strength, and reliable coating make them ideal for strong magnetic holding tasks, delivering secure grip and long-lasting performance.
