• Chemical Composition: Impurity elements (C, S, O, N) significantly degrade magnetic properties; high-purity raw materials are essential.
• Heat Treatment: Annealing temperature, holding time, and cooling rate directly determine permeability and coercivity. Hydrogen annealing or vacuum annealing at high temperatures (1100-1300°C) can achieve optimal magnetic performance.
• Processing Stress: Stamping, cutting, or other cold working operations introduce stress that reduces permeability. Final annealing is required to restore magnetic properties.
• Material Thickness: High-frequency applications require thinner materials (≤ 0.1 mm) to minimize eddy current losses.
• Operating Temperature: Magnetic performance degrades near the Curie point; exceeding this temperature causes permanent loss of ferromagnetism.
• Permendur 2V: Continuous operation ≤ 400°C, short-term exposure up to 500-600°C. Bs retention rate ≥ 87% at 400°C and ≥ 75% at 600°C.
• Permalloy (1J79): Continuous operation ≤ 100°C, short-term exposure up to 200°C. Permeability decreases significantly above 100°C.
• Electrical Silicon Steel: Continuous operation ≤ 150-200°C. Losses increase and magnetic properties degrade at higher temperatures.
