1J75 is a nickel-iron soft magnetic alloy containing around 75% nickel. This unique balance of composition provides extremely high permeability, making it an ideal choice where magnetic fields must be guided, concentrated, or shielded. Its low coercive force means it can be easily magnetized and demagnetized, ensuring efficiency in energy-sensitive applications. With a density of approximately 8.7 g/cm³ and operational reliability up to 500°C, 1J75 combines strength, stability, and durability.
