​​Frequently Asked Questions (FAQ) About Neodymium Rhombic Magnets​​

​​1. What are Neodymium Rhombic Magnets?​​

Neodymium Rhombic Magnets are rare earth magnets made from neodymium, iron, and boron (NdFeB) with a unique rhombic shape. They are known for their high magnetic strength, thermal stability, and resistance to demagnetization. These magnets are ideal for specialized applications such as elevators, where space constraints and performance reliability are critical.

​​2. What grades of Neodymium Rhombic Magnets do you offer?​​

We offer a range of grades including N35UH, N45UH, and others. These grades are selected based on the required magnetic strength, operating temperature, and corrosion resistance for your specific application.

​​3. Can I get custom-shaped or custom-sized Neodymium Rhombic Magnets?​​

Yes, we specialize in providing customized magnet shapes including rhombic and other geometries based on your technical drawings and specifications. Custom dimensions, tolerances, and magnetic orientations are fully supported.

​​4. What is the maximum operating temperature for these magnets?​​

Our AH grade Neodymium Rhombic Magnets can operate up to 220°C with minimal risk of thermal demagnetization, making them suitable for high-temperature applications.

​​5. How corrosion-resistant are your Neodymium Rhombic Magnets?​​

Our magnets exhibit excellent corrosion resistance with a weight loss of less than 10 mg/cm² under HAST 125±2, 0.25 MPA for 20 days. Additional surface coatings (e.g., NiCuNi, epoxy, zinc) can be applied for enhanced protection if required.

​​6. What is the minimum order quantity?​​

The MOQ is 1 piece for most custom orders. For standard grades and sizes, we support both small and large volume production runs.

​​7. How do I place an order for Neodymium Rhombic Magnets?​​

To ensure we meet your exact requirements, please provide details such as:

• Dimensions and tolerances (including drawings if available)

• Desired magnet grade (e.g., N35UH, N45UH)

• Magnetic orientation or polarization direction

• Coating preferences (if any)

• Operating temperature range

• Quantity needed and preferred delivery method

Please also let us know your delivery location or nearest port/airport for efficient logistics planning.
