Sintered neodymium magnets are much stronger than bonded neodymium magnets but provide less flexibility in terms of shapes that can be made. Magnetic orientation for sintered neodymium is anisotropic.

6 ALPHA MAGNET NEOMAG NEOMAG Sintered Neodymium Magnets Sintered neodymium is one of the most versatile rare earth magnets available. Dry granules of elemental materials are used to create sintered neodymium. Granules are compacted in a die and heated at high temperatures to fuse together. Sintered neodymium magnets are much stronger than bonded neodymium magnets but provide less flexibility in terms of shapes that can be made. Magnetic orientation for sintered neodymium is anisotropic. Neodymium magnets are lighter than samarium cobalt, however, typically they do have a lower acceptable temperature. Neodymium offers excellent value for applications that require a smaller- sized magnet. We stock patent licensed sintered neodymium magnets. Applications include electronic, industrial, automotive, aerospace, as well as wind power solutions. Advanced Capabilities PRECISION FORMING PROCESS The traditional forming method starts with large blocks of material to be cut into smaller blocks. In our proprietary process, the material is formed into an arc shape similar to the final product thus reducing waste and cost for arc-shaped magnets. These savings we pass onto you, the customer. The three unique steps in our new process are highlighted below: Steps in Precision Forming Process RADIAL ORIENTED RING MAGNET By creating just one single magnet specifically designed for your application, we are able to provide your company a product that is stronger, more reliable, and more efficient.

ALPHA MAGNET SAMARIUM COBALT SAMARIUM COBALT Samarium Cobalt Samarium cobalt is a rare earth material made by a powder metallurgical process.

Some of the advantages of using samarium cobalt is that it provides excellent temperature stability and as well as excellent corrosion resistance.

10 ALPHA MAGNET SAMARIUM COBALT SAMARIUM COBALT Samarium Cobalt Samarium cobalt is a rare earth material made by a powder metallurgical process. Manufactured using binders such as epoxy, samarium cobalt magnets are inherently very brittle. Users are discouraged from grinding material because dry remnants are a fire hazard. Some of the advantages of using samarium cobalt is that it provides excellent temperature stability and as well as excellent corrosion resistance. Because of this, typically coating or plating is not required. Samarium cobalt is excellent for operating in harsh environments were it will be exposed to the elements as well as high operating temperatures. Samarium cobalt excels in harsh environments common applications include marine, military, and aerospace. SAMARIUM COBALT GRADES Material Grade Energy Product (BH)max SmCo5 Sm2Co17 Low Temp Coeff.

11 ALPHA MAGNET MAGNETIC ASSEMBLIES MAGNETIC ASSEMBLIES Magnetic Assemblies & Sub-Assemblies Alpha Magnet specializes in producing magnetic assemblies and sub-assemblies per your requirement. From the selection of magnetic material to design services, we are happy to assist you throughout the whole process. CASE STUDY: CANON MAGNETIC ASSEMBLIES Cameras use two different types of image stabilization - digital and optical. Optical image stabilization is more sensitive than digital. By combining two assemblies into one, we were able to improve this key component of their product. The Problem Canon s original requirement was a shaft centerline with a magnetic orientation of 15. Originally, Canon would first complete the mold for the axle and card. After providing the magnets, they put the pieces together in their factory. This was very inefficient during the connection process the glue would easily move on the product. The result: the quality control failure rate was very high. The Solution We were able to offer Canon a solution through a precision injection process. First, we placed a magnet in the injection mold with a guaranteed angle of 15 (+/-0.5). Second, shallow grooves were added to increase adhesion of the glue and keep it from moving over time. The Result Canon was able to improve quality control pass rates as well as production efficiency. Having solved this problem concerning a key component to the camera, Canon was able to move forward. 11
