Application - Describe to us how and for what purpose the magnet will be used (a mechanical drawing is extremely helpful). This will be the basis for all further questions and discussions. Shape - Does your application require a specific shape of magnet? Most magnets are made in standard symmetrical shapes such as rings, discs, blocks, rods, and bars. Some types of magnets are machinable. Size - Are specific tolerances required for your application? Will the magnet be visible? The tolerances for our magnets are in accordance with International Magnetics Association/Magnet Materials...

Reference magnet, batteries, AC power adaptor, transverse probe and durable carrying case included. A. Part No. GM-2 - The DC Gaussmeter is a very accurate instrument useful in measuring the DC magnetic field intensity of magnets, magnetic devices and assemblies, as well as relays, electromagnets, motors, generators, loudspeakers, actuators, ferrite content in non-ferrous materials and more. Typical applications include magnet classification, analysis of magnetic circuitry and components, air shipment inspection, measurements of the earth’s field vectors, mapping and recording field...

(Rare Earth Magnets) Neodymium Iron Boron (Nd-Fe-B) or Neodymium magnets are extremely strong for their size. Shapes include rings, blocks, discs and custom. To prevent unwanted oxidation, neodymium magnets are usually finished with a zinc, nickel or epoxy coating. Manufacturing - In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field. ered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of the pole’s surface. The material is then...

Neodymium Discs with Adhesive Neodymium grade 35 nickel plated magnet discs with pre-applied .030 thick acrylic foam adhesive saves assembly time in a variety of applications. Liner Foam Adhesive Magnet Steel Disc Foam Adhesive Liner FSND50S 1. Magnet to Magnet - Use a North and a South magnet for added strength and “Snap-to” positioning. Magnets match up at same “Snap-to” spot every time. 2. Magnet to Steel Disc - Use a North magnet attracted to a steel disc for cost savings. Strength is slightly less than magnet to magnet. Magnet will attract to steel, but may not match up with same spot...

Please contact us and provide the shape, dimensions, tolerance, and grade of neodymium needed. Minimum quantities are required. To begin your order...

Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors. Manufacturing - A powdered mixture of strontium carbonate and iron oxide is injected into a wet or dry press for forming. During this process, a magnetic field is applied in the direction of preferred magnetization to orient the material and increase the magnet’s performance potential. This magnet is considered “oriented” (anisotropic). If not exposed to a magnetic field at time of...

Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. Alnico alloys are formed by casting process or are sintered. Cast Alnico - Cast alnico is melted and poured into a mold. Once solidified, the material is rough ground, then heattreated and cooled, sometimes within a magnetic field. When treated in the presence of a magnetic field, the magnet is called anisotropic (oriented). This orients the material to take on maximum magnetization and allows a higher gauss level. A cast magnet that is not heat-treated in a magnetic field is called...
