Because most customers use products with different specifications, the prices indicated online are not actual prices, and specific quotations need to be provided based on the customer's requirements. If you need customization, please contact our customer service and explain the size, brand, quantity, tolerance requirements, magnetization direction, etc. that you need to customize. We will customize production according to your requirements.

 

 

 

Please confirm the following before placing the order:

What material do you want? What performance is it?

What is the order quantity? What is the delivery time?

3. Do you want to magnetize? If magnetization is required, what is the method, axial or radial?

4.What is the surface treatment required? Zinc plating, nickel plating, nickel plating, copper nickel plating, epoxy, etc

5. Dimensions and tolerances? Can you provide CAD drawings

6. Are there any special requirements for salt spray testing? Do you have special requirements for thermal demagnetization? Please inform us of any other special requirements.

Characteristics: Neodymium iron boron permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Neodymium iron boron has extremely high magnetic energy product and coercivity, and the advantages of high energy density have made neodymium iron boron permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin equipment such as instruments, electroacoustic motors, and magnetic separation magnetization.

 

Material characteristics:

The advantages of neodymium iron boron are high cost-effectiveness and good mechanical properties; The shortcomings lie in the low Curie temperature point, poor temperature characteristics, and easy pulverization and corrosion. It must be improved by adjusting its chemical composition and adopting surface treatment methods to meet the requirements of practical applications.

Manufacturing process: The production of neodymium iron boron adopts powder metallurgy technology.
