  1. Overview • Magnets and magnetic materials are critical to our nation’s defense • Weapons systems that use magnetic materials: Thomas & Skinner is the world leader in high-performance magnets and magnetic materials used in strategic weapons systems

  2. Strategic DefenseApplications: Magnetics • Aegis Radar -- used widely by Army and Navy • Valves in nuclear submarines • Hellfire missile guidance systems • Military aircraft, including F-18, F-22, F-35 • Power klystrons • ground-based earth-to-satellite communications amplifiers (KPA’s) and troposcatter communication terminals • Minuteman IV ICBM

  3. Hard (Permanent) Magnets Magnetic field WITHOUT an electric current Three general types: Alnico Rare Earth SmCo NdFeB Hard Ferrites Soft Magnetic Materials Magnetic field ONLY with an electric current Multiple types, including: Electrical steel Soft Ferrites Powdered iron Magnetics Crib SheetHard Magnets vs Soft Magnetic Materials

  4. Thomas & Skinner, Inc. 1901 Company founded by John Esterline, EE professor at Purdue University 1923James Thomas & O.H. Skinner acquired magnetics division

  5. Thomas & Skinner, Inc. Today Employee-owned manufacturer of magnetic materials headquartered in Indianapolis, Indiana. Markets:

  6. Thomas & Skinner, Inc. Goal: • Provide the highest quality, domestically- produced custom magnetic components • Stay close to customer base • Maintain technological advantage • Avoid low-technology, low-price segments • low-quality and/or high-volume applications Strategy: Compete with anyone in the world for high- quality, high-performance magnetics, bar none

  7. Thomas & Skinner, Inc. • Soft ferrites • Fairfield, NJ -- 68 Products: • Alnico magnets • Transformer laminations Employees: • Indianapolis, IN -- 136 • Osgood, IN -- 17 Exports to:

  8. Alnico • Hard (permanent) magnet • Known for stability and operating temp. range • Max operating temp: 550° C (1000° F) • Base materials: • Aluminum • Nickel • Cobalt • balance of Iron • Cast and Sintered in Indianapolis

  9. Transformer Laminations • Soft (non-permanent) magnetic material • Regulates the voltage in electrical devices • Wrapped with copper wire • Creates a magnetic field • Base material: electrical steel (3.25% silicon) • US Mills: • AK Steel • Allegheny Ludlum • Products stamped in Indianapolis

  10. Soft Ferrites • Soft (non-permanent) magnetic material • Regulates voltage in electrical devices • Wrapped with copper wire • Creates a magnetic field • Antennas • Sensors • Base material: MnZn and NiZn (ceramics) • Powder production and machining • New Jersey
