Engineering Magnets (NdFeB, Ferrite)

Engineering Magnets (NdFeB, Ferrite)

Silvari Group supplies high-performance engineering magnets, including Neodymium-Iron-Boron (NdFeB) and Ferrite types, designed for modern manufacturing and precision engineering.

These magnets are essential in applications requiring strong magnetic performance, dimensional stability, and long-term reliability.

Product Overview

• NdFeB Magnets (Neodymium Magnets) – Known as the most powerful type of permanent magnet, NdFeB offers excellent magnetic strength, making it ideal for compact or high-performance designs.
• Ferrite Magnets (Ceramic Magnets) – Recognized for their corrosion resistance and temperature stability, ferrite magnets are suitable for applications in electric motors, loudspeakers, magnetic separators, and general-purpose devices.

Key Features

• Available in a broad range of shapes
• Custom shapes and coatings upon request
• Stable magnetic performance over long-term use
• Suitable for electrical, mechanical, and consumer product designs

Available Grades & Forms

NdFeB Magnets:

• Sintered NdFeB Magnets – The most widely used, produced by heating compressed powder to create a dense, rigid, and high-performance magnet.
• Bonded NdFeB Magnets – More flexible and can be formed into complex shapes, as they are mixed with a polymer binder.
• Hot-Pressed NdFeB Magnets – Offering a combination of high performance, dimensional precision, and excellent corrosion resistance.

Ferrite Magnets:

• Sintered Ferrite Magnets – Produced by a high-temperature process, these magnets are strong and hard and used in many common applications.
• Bonded Ferrite Magnets – Offered in custom shapes with better chip resistance, as they are mixed with a polymer binder.

Both NdFeB and ferrite magnets are available in a broad range of shapes, including blocks, rings, discs, and arcs, with custom geometries available upon request.

Applications

• Electric Motors & Generators – Providing the magnetic foundation for efficient energy conversion in industrial machinery, automotive systems, and compact motor assemblies.
• Sensors – Delivering stable magnetic fields for motion detection, positioning, and control systems requiring accuracy and reliability.
• Acoustic Systems – Applied in speakers, microphones, and other sound devices, ensuring consistent sound quality and magnetic precision.
• Renewable Energy Devices – Powering wind turbines and EV powertrains, enabling sustainable energy solutions through high-efficiency magnetic performance.
• Precision Instruments – Supporting analytical, measurement, and calibration systems that demand dimensional stability and repeatable magnetic output.
• Consumer Electronics – Used in compact devices such as smartphones, headphones, and small appliances where performance and efficiency are key.
