EFINEA Alloy 79 – Soft Magnetic Alloy
EFINEA Alloy 79 (UNS N14080), widely recognized by trade names such as HyMu 80, Magnifer 7904, Hipernom, and Moly Permalloy 80, is a premier soft magnetic, unoriented, nickel-iron-molybdenum alloy. Its composition, approximately 79%-82% nickel, 3.5%-6.0% molybdenum, and the balance iron, contributes to its exceptional magnetic properties. This alloy boasts remarkably high initial and maximum permeability coupled with minimal hysteresis loss, making it the preferred choice for demanding applications like EMI shielding, transformers, and miniature electronics. Available in various forms including rod, sheet, coil, and square bar, EFINEA Alloy 79 offers versatility to meet diverse project requirements.
EFINEA Alloy 79 is also known by the following trade names and manufacturers:
- HyMu®80 (Carpenter Technology Corp.)
- Magnifer® 7904 (VDM GmbH)
- Moly Permalloy® 80 (ATI)
EFINEA Metals’ primary mill manufacturers of EFINEA Alloy 79 are Carpenter Technology Corp, Reading, PA and VDM GmbH, Werdohl, Germany.
The extremely high initial and maximum permeability, combined with minimal hysteresis loss, distinguishes EFINEA Alloy 79. These characteristics make it indispensable for a wide range of applications, including:
- Electro Magnetic Interference (EMI) shielding from low-frequency magnetic fields.
- Transformer cores, ensuring efficient energy transfer and minimal losses
- Ground fault circuit interrupters (GFIs) for enhanced electrical safety
- Tape-wound toroids and laminations for precise magnetic control
- Miniature transformers and other applications where small size and low weight are critical
