1 NATIONAL MAGNETICS GROUP, INC. MANUFACTURERS OF MAGNETIC AND ADVANCED MATERIALS AFFILIATE: TCI CERAMICS, INC. To Whom it May Concern: Enclosed please find an electronic version of our existing catalog along with some newer inserts. We apologize that our new and improved catalog has been so long in the making. We anticipate having this catalog available in late 2003 along with a complete web site. We would like to point out some changes to the attached catalog and our organization since printing ~ 10 years ago: Area code changed to: 610 contact established: sales@magneticsgroup.com Website obtained: Material Data sheets (complete with curves) available on request Expanded selection of: materials, capabilities, tooled shapes Continuing improvements in quality: compliant with ISO9000/QS9000 Acquired Ceramic 1 (F-340) permanent magnet product line from Steward, Inc. Acquired soft ferrite extruded product line from Fair-Rite Products Corp. Added ~ 10,000 SF of mfg. space to existing 36,000 SF facility in Bethlehem, PA Operations from our west coast subsidiary CMI Technology, Inc. consolidated into our Bethlehem, PA facility Started subsidiary (3C Microwave) manufacturing microwave ferrite and dielectric materials, including super narrow line width garnets Acquired TRAK Ceramics, Inc. in Hagerstown, MD (from TRAK Communications Inc.), a manufacturer of microwave ferrites, dielectrics and resonators for the wireless industry as well as specialty ceramic materials for thermal deposition (visit: A new company has been formed TCI Ceramics, Inc. from the combination of 3C Microwave and TRAK Ceramics, Inc. Subsidiary/affiliate Ceramic Elements Co. and CMI Technology, Inc. have been merged into National Magnetics Group, Inc. to improve efficiencies. Started offering full range of magnet materials (oriented ceramic, rare earth, alnico, flexible, etc.). One thing that has not changed is our commitment to customer service. We continue to strive to help solve our customers problems with regard to: rapid delivery and/or tooling, quality, custom shapes, secondary machining, tight tolerances you name it! We look forward to helping you with your requirements. Please contact us. Very Truly Yours, National Magnetics Group, Inc.
