Product Description
High Permeability Soft Magnetic Alloy
Permalloy 80 is a high-performance nickel-iron-molybdenum soft magnetic alloy with approximately 80% nickel, 15% iron, and 5% molybdenum composition. This vacuum-melted material delivers exceptional magnetic properties including maximum permeability and minimal core losses at low field strengths, making it ideal for compact, lightweight magnetic core and shielding applications.
Key magnetic characteristics include relative permeability up to 250,000, near-zero magnetostriction, significant anisotropic magnetoresistance, low coercive force, minimal hysteresis loss, and reduced eddy-current losses. These properties enable reliable performance in thin film applications where variable stresses could otherwise compromise magnetic characteristics.
Primary Applications
- High sensitivity and small power transformers
- Magnetic amplifiers and relays
- Chokes and magnetic heads for recording devices
- Magnetic shields and tape wound cores
- Cut cores and laminated cores for weak magnetic fields
