Wholesale Block Neodymium Magnet | Fullzen Technology

Short Description:

Our neodymium block magnets are among the strongest permanent magnets available, offering a high level of magnetic performance and versatility. Made from a neodymium-iron-boron (NdFeB) alloy, these rectangular or square magnets are ideal for a wide range of industrial, commercial, and technical applications. Their shape makes them particularly useful for systems requiring a flat magnetic surface and directional force.

Key Features:

Superior Magnetic Strength: Neodymium block magnets offer high energy density, with Br (remanence) values up to 1.45 Tesla and energy products ranging from 33 MGOe to 52 MGOe. Their strength allows for maximum performance in compact spaces.
Material Composition:
- Neodymium (Nd): 29-32%
- Iron (Fe): 64-68%
- Boron (B): 1-2%
- Trace elements like Dysprosium (Dy) for enhanced temperature resistance can be added based on requirements.
Durability: Coated with nickel-copper-nickel (Ni-Cu-Ni), neodymium block magnets are highly resistant to corrosion and wear, ensuring long-term performance in a variety of environments. We also offer epoxy, gold, zinc, and rubber coatings for enhanced resistance in specific applications.
High Precision: Manufactured with tight tolerances, typically ±0.05mm, these block magnets are designed for precision applications where exact dimensions and consistent magnetic performance are crucial.
Temperature Tolerance: Standard block magnets can withstand temperatures up to 80°C (176°F). For applications requiring higher operating temperatures, we offer special grades that perform efficiently up to 150°C (302°F).
