Permanent Magnets From Magma Magnetic Technologies
Permanent Magnets come in various compositions, including Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), Alnico, and Ferrite (also known as ceramic).
Rare earth magnets, such as NdFeB and SmCo, offer superior strength, making them ideal for applications requiring high energy or compact yet robust magnets. SmCo magnets are particularly suitable for use in higher-temperature environments.
Ceramic magnets provide a cost-effective solution without compromising strength and are often favored for mass-production applications. Alnico magnets exhibit excellent temperature stability.

Rare Earth Neodymium Magnets (NdFeB)
Since 1984, Rare Earth Neodymium magnets (NdFeB) have been utilized across various industries. Renowned for their exceptionally high magnetic energy, Neo magnets find application in scenarios demanding powerful magnets with a focus on size and weight reduction. This preference for NdFeB magnets over bulkier Ferrite magnets are attributable to their superior strength-to-size ratio.
Applications for Rare Earth Neodymium Magnets include electronics, automotive, medical, clean tech energy, magnetic separators, magnetic bearings, and others.
Samarium Cobalt Magnets (SmCo)
Samarium Cobalt Magnets are potent, rare earth magnets created from an alloy of samarium and cobalt that have been accessible since the early 1970s. Their emergence facilitated the progress and widespread application of Neodymium. While they may carry a higher cost and exhibit slightly less strength compared to Neodymium magnets, Samarium Cobalt magnets possess a higher Curie temperature.
The advantages of SmCo magnets include high resistance to corrosion and demagnetization, high energy, and good temperature stability. They are an excellent choice for cryogenic systems, military, and space applications.
Hard Ferrite Ceramic Magnets
Hard Ferrite Ceramic Magnets were first developed in the 1960s. They currently account for approximately 75% of global magnetic consumption due to their widespread availability and cost-effectiveness. Also, the manufacturing process for Hard Ferrite Ceramic Magnets enables the orientation of the magnetic field to be established during magnet production.
Magma Magnetic Technologies specializes in manufacturing Hard Ferrite (anisotropic) using a wet-pressing technique, followed by precision cutting and grinding of the magnets utilizing an electroplated diamond grinding wheel.
AINiCo Permanent Magnets
AlNiCo materials primarily consist of Aluminum, Nickel, and Cobalt alloys. They are exceptional for their temperature stability, high residual inductions, and relatively elevated energy levels. AlNiCo alloys exhibit some of the highest temperature tolerances among magnetic materials commercially available. They find extensive use in applications requiring operational temperatures of up to 450°C.
Radial Sintered Ring Magnets
Radial sintered ring magnets, crafted from Neodymium, undergo modification to align multiple magnetic fields in diverse directions within a singular ring. This radial magnetization substantially enhances the magnetic force of the ring, resulting in the creation of the most potent NdFeB ring magnet currently accessible for industrial and commercial applications.
This significant advancement is poised to transform the magnet market by providing a novel solution to a recognized requirement for demanding requirements such as motor applications.
