Custom Rectangular Neodymium Magnet – Process Guide
Our production process is as follows: After the customer provides drawings or specific requirements, our engineering team will review and confirm them. After confirmation, we will make samples to ensure that all products meet the standards. After the sample is confirmed, we will carry out mass production, and then pack and ship to ensure efficient delivery and quality assurance.
Our MOQ is 100pcs,We can meet customers' small batch production and large batch production. The normal proofing time is 7-15 days. If there is magnet stock, the proofing can be completed. within 3-5 days. The normal production time of bulk orders is 15-20 days. If there is magnet inventory and forecast orders, the delivery time can be advanced to about 7-15 days.
What Are Rectangular Neodymium Magnets?
Definition
Rectangular neodymium magnets, also known as neodymium bar magnets or block magnets, are high-performance Ndfeb magnets engineered with a rectangular form factor. Composed of neodymium, iron, and boron, these strong magnets offer exceptional magnetic strength relative to their size, outperforming traditional magnets like ferrite counterparts.Available in diverse specifications – from small and thin designs to heavy-duty N52 neodymium blocks – they cater to a wide range of applications. Grades including N35 magnet, N42 neodymium , and N52 neodymium define their performance, with N52 being the most powerful option for demanding uses.
Shape types
"Rectangular" is an umbrella term that encompasses a variety of refined geometric profiles, each with distinct magnetic field characteristics and application scenarios. Understanding these subtypes is crucial for selecting the most suitable powerful magnet for your project.It is centered around a rectangular geometric framework; essentially, it involves adding functional designs to the basic types to meet the specific installation and application needs of different industries.
Key Advantages：
Strong magnetism & space-saving: Small in size yet high in magnetic force, suitable for space-constrained scenarios.
Stable performance: The rectangular structure ensures uniform magnetic field, ideal for precision needs such as sensors and magnetic latches.
Flexible customization: Size, coating and magnetization direction can be adjusted as needed, meeting different scenarios like industrial and daily use.
Durable & long-lasting: Made of high-purity NdFeB material with protective coatings , it is rust and wear resistant.
Versatile: industrial sector, electronic field, precision equipment, and automotive field.

FAQs about Rectangular Neodymium Magnets
We offer flexible MOQs, starting from small batches for prototyping to large-volume orders.
Standard production time is 15-20 days. With stock, delivery can be as fast as 7–15 days.
Yes, we provide free samples for qualified B2B clients.
We can provide zinc coating, nickel coating, chemical nickel, black zinc and black nickel, epoxy, black epoxy, gold coating etc...
Thicker magnets generally offer higher pull force, but optimal thickness depends on the application.
Yes, with appropriate coatings (e.g., epoxy or parylene), they can resist corrosion and perform reliably in harsh conditions.
We use non-magnetic packaging materials and shielding boxes to prevent interference during transit.
Professional Knowledge & Buying Guide for Industrial Buyers
Magnetic Strength vs. Thickness
The thickness of a Rectangular Neodymium Magnets significantly influences its magnetic output. Thicker magnets generally provide higher pull force, but the relationship is not always linear. Selecting the right thickness involves balancing space constraints with performance requirements.
Coating Selection & Lifespan in Rectangular Neodymium Magnets
Different coatings offer varying levels of protection:
- Nickel: Good overall corrosion resistance, silver appearance.
- Epoxy: Effective in humid or chemical environments, available in black or gray.
- Parylene: Superior protection for extreme conditions, often used in medical or aerospace applications.
Selecting the correct protective coating is crucial. A nickel plating is common for humid environments, while more resistant coatings like epoxy, gold, or PTFE are essential for acidic/alkaline conditions. Coating integrity without damage is paramount.
