Different Types of Magnets in Magnetic Assemblies

Posted by bcmagnets on August 14th, 2014

Usually a magnetic assembly incorporates magnet alloy and non-magnet material. However the magnet alloy is very hard and thus even simple features are difficult to incorporate into the alloy. For forming the housing or magnetic circuit elements mounting and application specific features are effortlessly built in the non-magnetic materials. It leads to the non-magnet elements buffering the brittle magnet material from mechanical stress and augment the over-all magnetic strength of the magnet alloy. Magnetic Assemblies at BC Magnets includes:

Building permanent magnet assemblies is possible from a production run of one piece to tens or a few hundred per month. With accurate design, development and prototyping the customers can receive appropriate customized products at planned low cost reductions. You BC Magnets to browse the sophisticated assemblies they build on a regular basis at lower cost, faster pace and better quality. The company takes pride in producing some of the best magnetic assemblies for their clients.

If you are looking for good resistance to demagnetization as well as lower cost then Ferrite magnets are best solution for your needs. They are sintered permanent magnets composed of Barium or Strontium Ferrite. These magnets are very hard and brittle, and require specialized machining techniques. Due to their low cost, they offer a variety of applications that range from motors and loudspeakers to toys and crafts, and are the most widely used permanent magnets in the present day. Since they have quality of electrically insulating they are called Ceramic Magnets. They are darker grey in colour.

Alnico magnets are hard and brittle. Thus machining or drilling is not possibly accomplished by ordinary methods. Holes are usually cored in at the foundry, and magnets are cast close to final size and then finish machined to closer tolerances. They are an alloy made mainly from a combination of Aluminium, Nickel, Cobalt and Iron plus varying levels of Copper, Titanium and Niobium.

SMCo magnets or Samarium Cobalt magnets offer designers a tremendous combination of exceptionally high magnetic properties, excellent thermal stability and tremendous corrosion resistance. They are a part of the rare earth group of permanent magnets and are an excellent choice for compact designs where high temperature environments may be present.

Neodymium Magnets or NdFeB magnets are made from an alloy containing, amongst others, the elements Neodymium, Iron and Boron (NdFeB). Thus they are the strongest type of magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.
