Custom Neodymium Bar Magnets – 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 Neodymium Bar Magnets?
Definition
Neodymium Bar Magnets：as the name suggests, is a magnet with a shape similar to a rectangular prism. This means that the bar magnet is elongated in shape. NdFeB bar magnets are powerful rectangular rare-earth magnets crafted from Nd-Fe-B alloy, delivering intense linear magnetism for motors, sensors, and separators; they require coating for corrosion resistance due to brittleness.
Shape types
The shape types of bar magnets can be classified from three dimensions: cross-sectional shape, overall structure, and special customized form. Different shapes are suitable for different industrial application scenarios, such as rectangular bar magnets, cylindrical bar magnets, trapezoidal cross-sectional bar magnets, and arc-shaped bar magnets.
Key Advantages:
Compact size: suitable for modern equipment with strict requirements for space and weight.
High cost-effectiveness: can further reduce costs during mass production.
Can be processed specifically: can be made into various shapes and sizes through craftsmanship, with wide adaptability.
Good performance stability: After coating treatment, it can prolong the service life.

Technical Insights & Best Practices for Neodymium Bar Magnets
Why NdFeB (Neodymium Iron Boron) Is the Strongest Commercial Permanent Magnet
NdFeB is the strongest commercial permanent magnet because its unique Nd₂Fe₁₄B crystal structure provides an unparalleled combination of high magnetic saturation and extreme resistance to demagnetization, which engineers have successfully translated into bulk magnets with the highest maximum energy product (BHmax) achievable on the market.
Coating Selection & Lifespan in Neodymium Bar 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.
