Neodym-Eisen-Bor (NdFeB) ist weit verbreitet in den Bereichen Automotive, Industrial Automation, Erneuerbare Energien etc.

Kunststoffgebundene Ferrite

Seit 1950 produziert das Unternehmen Magnetsegmente und Magnetpulver in Spitzenqualität. Mit 80 Mitarbeitern ist die Tridelta Hartferrite GmbH heute einer der bedeutendsten Hersteller von magnetischen Werkstoffen und keramischen Dauermagneten in Europa.

Die wesentlichen Rohstoffe für AlNiCo-Magnete sind Eisen, Aluminium (~9%), Nickel (~13%) und Kobalt (~24%). Außerdem werden verschiedene andere Elemente zugemischt. Gesinterte AlNiCo-Magnete werden durch ein Sinterverfahren unter Hochtemperatur und Schutzgasatmosphäre hergestellt. Dazu wird das Material in einem Pulvermetall-Prozess vorbereitet. Unser Sortiment umfasst gesinterte AlNiCo-Magnete bis zu einem Gewicht von 150g. Der fertige Magnet ist sehr hart und kann nur mit Diamantwerkzeugen oder durch Erodieren bearbeitet werden. AlNiCo-Magnete zeichnen sich durch gute Korrosionsbeständigkeit aus. Sie haben einen sehr geringen (negativen) Temperaturkoeffizienten und können bei Temperaturen von -250 bis +500°C eingesetzt werden. Damit sind diese Magnete für den Einsatz in Hochtemperatur-Anwendungen hervorragend geeignet. Die Remanenz von AlNiCo-Magneten liegt, je nach Legierung, zwischen ca. 0,70 Tesla und 1,1 Tesla. Die Remanenz ist damit der von NdFeB-Magneten vergleichbar. Allerdings ist die Koerzitiv-Feldstärke mit 50 - 150 kA/m etwa um den Faktor 10 kleiner als bei NdFeB-Magneten. AlNiCo-Magnete sind auch als kunststoffgebundene Magnete verfügbar.

Gummimagnete werden im Walz- oder Extrusionsverfahren hergestellt und können doppelseitig verklebt oder mit PVC, Latex oder PET verbunden werden, um sie danach zu bedrucken. Sie bestehen aus einer speziellen Mischung aus Ferrit- und Kunstkautschukpulver. Die Materialdichte von Gummimagneten beträgt circa 3,5 g/cm³. Durch die Kalibrierung der Verbindungen in der Produktionsphase können unterschiedlichste Leistungen erzielt werden. Wir bei Calamit können zudem mit verschiedenen Polteilungen magnetisieren, um eine bessere Kontakthaftung zu erzielen. ---

Typical Applications for Soft Ferrite Magnets Power conversion Line filters Radio frequency applications TransformersIt is expected that the customer will know the size, shape and performance Soft Ferrite Magnets Soft ferrite are not permanent magnets. They carry magnetism (like mild steel) but as soon as the magnetic field is removed, the magnetism disappears. Soft ferrite are popular as transformers (to change the voltage from primary to secondary windings). So soft ferrite are often called transformer ferrite. Soft ferrite exist as toroids (rings), C shapes, E-shapes, curved shapes, etc. Other shapes are possible. They often have performance criteria such as permeability and inductance. Advantages & Disadvantages of Soft Ferrite Magnets Advantages * Carry magnetism effectively with low losses * Can handle alternating currents Disadvantages * Have different properties such as inductance and permeability so care is required to get a correct material type * It will be expected that the customer knows exactly what they require Typical Applications for Soft Ferrite Magnets * Power conversion * Line filters * Radio frequency applications * Transformers It is expected that the customer will know the size, shape and performance characteristics of the soft iron material that they require.

Hochwirksame nanokristalline LEISTUNGSÜBERTRAGER Kerne. Nanokristallines Material ist extrem verlustarm und somit prädestiniert für die Anwendung der „Leistungsübertrager“. Nanokristallines Material ist extrem verlustarm und somit prädestiniert für die Anwendung der „Leistungsübertrager“. Unsere LÜ-Kerne ermöglichen ein sehr leistungsfähiges Design mit sehr geringen Verlusten bei hohen Frequenzen. Durch die Epoxy Beschichtung, die direkt am Bandmaterial aufliegt, ist die Wärmeabfuhr optimal. Aufgrund einer geringen Magnetostriktion und sehr guten HF-Eigenschaften, sowie der ausgezeichneten Temperaturbeständigkeit des Materials erhalten Sie optimale Bedingungen für ein besonderes Design Ihres Leistungsübertragers. Beschichtung: epoxy orange (UL E345773) Verluste @300mT, 100kHz, sin: <5W/core Gewicht: 395 gr

Filterkerne aus nanokristallinem Material zeichnen sich besonders aus durch die Einstellbarkeit sehr hoher Permeabilitäten bei kleinster Bauweise, einer Sättigungsflussdichte Bs = 1,2T - und verschwindender Sättigungsmagnetostriktion (<5ppm) sowie einer extrem guten Temperaturbeständigkeit, die bis 130°C nahezu konstant bleibt. Filterkerne aus nanokristallinem Material zeichnen sich besonders aus durch die Einstellbarkeit sehr hoher Permeabilitäten (ca. 20.000 – 200.000μ) bei kleinster Bauweise, einer Sättigungsflussdichte Bs = 1,2T und verschwindender Sättigungsmagnetostriktion (<5ppm) sowie einer extrem guten Temperaturbeständigkeit, die bis 130°C nahezu konstant bleibt. Besonders in Zeiten neuer Technologien durch rasend schnell schaltende IGBTs (z. B. Silicon Carbide ‚SiC‘ oder Gallium Nitride ‚GaN‘) werden die Anforderungen an die EMV Filter immer größer und machen den Einsatz nanokristalliner Ringbandkerne für die Filtertechnologie immer unerlässlicher. Durch deren besondere Eigenschaften kann nicht nur Platz und Gewicht eingespart werden, sondern auch eine extrem gute HF/RF Dämpfung erzielt werden.
