Full Range of Magnetic Materials

Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), Aluminium Nickel Cobalt (AlNiCo), Ferrite — we offer a variety of permanent magnetic materials, both as standard catalogue items and as tailored designs based on your specifications.

Powerful Neodymium Magnets (NdFeB)

Known for their high temperature resistance, these ‘rare earth magnets’ are ideal for heavy duty applications. Goudsmit UK’s Neoflux® brand is one of the strongest and most powerful magnetic materials available today.

Characteristics:

Energy product above 50 MGOe possible
Lower resistance to corrosion
Applications: Automotive, electronics (sensors, speakers, scanners), medical (scanners), magnetic separators and other heavy industries

See Grade Table For Neo Magnetic Capabilities.

High-Stability Samarium-Cobalt Magnets (SmCo)

Permanent magnets made of samarium and cobalt are the ideal choice in mission critical applications. With 7 times the strength of ferrite, they offer excellent magnetic characteristics. They offer high stability, effective over a higher range of temperatures with enhanced resistance to corrosion.

Characteristics:

Energy product 18–30 MGOe
Low temperature coefficient
High corrosion-resistance
Applications include: Medical implants, high temperature pumps, sensors and turbo machinery

See Grade Table For SmCo Magnetic Capabilities.

Corrosion-Resistant AlNiCo Magnets

Once the strongest type of permanent magnetic material available, AlNiCo magnets continue to be popular for their corrosion resistance and use in high-temperature applications. Made of aluminium (Al), nickel (Ni) and cobalt (Co), they are typically cast and can therefore, take complex forms. Goudsmit UK offers a variety of shapes and sizes to meet your needs.

Characteristics:

Magnets can be over moulded
Complex shapes possible
High temperature resistance
Applications include: Anti-lock braking systems (ABS), reed switch based products, rotating machinery, guitar pick-ups

See Grade Table For AliNiCo Magnetic Capabilities.

Cost-Efficient Ferrite Magnets

Ferrite magnets offer enhanced resistance to demagnetisation, are stronger than their AlNiCo counterparts and an affordable choice. Made of chemical compounds consisting of ceramic materials with iron (III) oxide (Fe2O3), they are used in a variety of applications. Goudsmit UK specialise in the supply of hard ferrites which have a higher coercivity and remanence after magnetisation.

Characteristics:

Affordably priced
Energy product of 1 to approx. 4.3 MGOe
High corrosion-resistance
Applications include: Loudspeakers, microwaves, magnetic filters and drives for pumps

See Grade Table For Ferrite Magnetic Capabilities.
