Custom & Standard Permanent Magnet Shapes / Sizes

 

Precision Magtech prides itself in providing customers with the specific permanent magnet solution for the application requirements. We have standard and custom magnet shapes and sizes. Machine magnet shapes based on customer requirements and we continue the tradition of offering customers with a variety of magnet options.

As an all-in-one magnetic solution provider, Precision Magtech is able to fabricate standard permanent magnet shapes and sizes in prototype or production quantities.

  • Material Grades

There are a number of major families of permanent magnets available. They range from ferrite, which is low cost and low energy, to rare earth materials, which are more expensive and offer higher performance. Many factors affect the choice of magnetic material, such as operating temperature, size, weight constraints, environmental concerns and required magnetic energy. More information on our specific magnet materials is available through the links below.

  • Magnetization Patterns

 

Isotropic magnets, such as Bonded Nd-Fe-B, are unoriented and have no preferred direction; therefore it is possible to magnetize them in any direction. Almost all other materials are anisotropic and have a preferred direction of magnetization. They will exhibit the best magnetic properties when magnetized in the direction of the grain. Higher magnetic flux densities can be achieved with anisotropic magnets that are magnetized in their direction of orientation than with isotropic magnets.

The magnetization patterns for your project can be created with the following orientations:
