Custom Magnets

Some common applications custom include...

• Arc Magnets
• Motor Magnets
• High Temperature Magnets
• Rubber Strip Magnets
• Adhesieve Backed Magnets
• Molded Magnets
• Sensor or Trigger Magnets

If you need a custom magnet to your exact specifications, you have come to the right place.
We can do short run, and large volume production runs.

We do not have minimum orders for custom magnets, however pricing will be reflective of the quantity purchased due to startup and production costs.

We will need all of the following information when quoting your special order magnets.
1) Exact Dimensions. We will need clear accurate drawings, which show all critical dimensions
    as well as the direction of magnetization.  Please use PDF, STEP, SLDPRT, SLDASM, SLDDRW, IGES, PARASOLID, PRO/E, VRML, STL, DXF, eDrawing, JPG, BMP or TIFF formats.
2) Magnet Grade. Please indicated the grade of magnet (N40, 42SH etc)  See Grade Chart
3) Magnet Type. Please indicate the type of magnet you wish quoted.
    (NdFeB, AlNiCo, SmCo, Ferrite)
4) What is the desired working temperature?
5) Quantity. What will be your initial requirement? What will be your monthly/yearly needs
    for this same product?
6) Application.  What is the basic use of the magnet in your application?  What problems are you trying to solve with the magnet?
7) Time. When do you need this by? Normal custom magnet prototyping is 3-4 weeks. Please
    send your special and custom magnet requests to

AVAILABLE MATERIALS

AVAILABLE MATERIALS	MGOe RANGE	SHORT DESCRIPTION
Sintered NdFeB (Neodymium Iron Boron)	33-52	Neodymium Magnet (also known as NdFeB, NIB, or Neo magnet). This material is currently the strongest known type of permanent magnet, but has a lower operating temperature than SmCo type magnets.
SmCo (Samarium Cobalt)	16-30	SmCo magnet is a strong permanent magnet made of an alloy of Samarium and Cobalt.  SmCo is slightly less powerful than NdFeB, but has a higher temperature options, and is also higher cost.
Bonded NdFeB (Neodymium Iron Boron)	2-13	Bonded Neo magnets are made of NdFeB particles, mixed with a polymer and either compression or injection molded into bonded magnets. Bonded NdFeB is less powerful than sintered NdFeB, but has more options for shape, and tolerance.  Often used for small rotary motors.
AlNiCo (Aluminum Nickel Cobalt)	1.5-6	AlNiCo magnets are weaker than NdFeB and SmCo but are also less expensive.  This material can be cast or sintered into various shapes. This is the type of material often found in horseshoe magnets.
Ceramic (Ferrite)	0.8-4.5	Ferrites are usually non-conductive ferromagnetic ceramic compounds derived from oxides of Iron and Strontium or Barium. They are cheap, and are widely used in household products such as refrigerator magnets.
Flexible (Rubberized Magnets)	0.5-1.6	Flexible magnets can be molded and cut to a variety of shapes and sizes.  They can be produced in many thicknesses and are available in adhesive-backed or plain material.  Often found on business card magnets.
