Bunting Magnetics Co. has one of the largest selections of in-stock permanent magnets and holding assemblies available and stocks hundreds of Rare Earth, Alnico, and Ceramic magnets, ready for immediate shipment. The firm also custom cuts magnets to purchaser specifications.

Rare Earth Magnets: Bunting offers an expanded line of high-energy Neodymium and Samarium Cobalt permanent magnets and Rare Earth holding assemblies. The Neo Assemblies come in concentric and two- and three-pole configurations and are corrosion-resistant.

Neodymium Rare Earth magnets offer very high energy and holding power in compact sizes and light weights. Bunting Neodymium-Iron-Boron magnets are stocked in six grades and dozens of standard sizes and shapes, including bar and plug shapes. The selection includes a heat-resistant grade plus corrosion-resistant nickel-plated Neodymium magnets.

Samarium Cobalt Rare Earth magnets are ideal for use in many high-energy and high-temperature applications. These magnets combine energy products that approach those of Neodymium grades with temperature stability similar to that of Alnico magnets.

Ceramic Magnets: Permanent Ceramic Magnets in grades 5, 8, and 1 are the most widely specified magnets for commercial use. Bunting Magnetics Co. has them in many shapes and sizes for a wide range of applications – in stock and ready to ship. Low cost, light weight, a relatively high energy product, and good resistance to demagnetization foster the widespread use of these popular magnets. Ceramic Magnets retain about 45 percent of their room-temperature characteristics at 350º F (177º C) and don't become completely demagnetized until approximately 840º F (449º C). They can, however, be remagnetized for continued use if not exposed to temperatures above 1800º F (982º C).

Ceramic magnetic material is hard and brittle and should be cut before it is magnetized. Bunting can shape and size Ceramic Magnets to precision tolerances. The company offers custom fabrication to buyer specifications and can even provide wafer-thin strips too delicate for most suppliers to machine.

Alnico Magnets: Bunting Magnetics Co. stocks the most popular grades of Alnico Magnets in many shapes and hundreds of sizes. Shapes include round and rectangular bars, U-shaped, horseshoe, separator, channel, ring, disc, plug, and rod. Alnico magnets are the ideal choice for applications exposed to operating temperatures above 400º F (204º C). Up to 1000º F (538º C), they maintain about 85 percent of their room-temperature magnetic properties, and losses in magnetization are reversible.

Alnico Magnets derive their name and their magnetic properties from the aluminum, nickel, and cobalt from which they are made. They have the widest range of temperature stability of any standard magnetic material. Other characteristics include high induction as well as relatively high energy. Manufacture is by sintering or casting.

Both cast and sintered Alnico Magnets are hard and brittle and require skillful handling. Bunting engineers assist with special orders, and the company offers custom fabrication to buyer specifications within the limits for which Alnico Magnets are suitable.

Flexible Magnetic Strips and Sheets: Bunting Magnetics Co. offers a wide variety of flexible magnetic strips and sheets. A few of the many applications for magnetic strips are latches or catches, gaskets, door seals, tool holders, and holding fixtures. For signs, charts, displays, shelf labeling, and novelties, they're a reusable alternative to adhesive or fasteners.

Flexible magnets can be bent, twisted, or flexed to conform to any surface without loss of magnetic energy, and can be cut, slit, punched, drilled, or machined to meet many product design specifications. Bunting can slit-to-width, cut-to-length, or laminate adhesives or vinyl according to the end user's requirements.
