Magnetic materials are the foundation of modern electronics and power systems. Among them, nickel-iron precision alloys play an essential role in delivering stability and efficiency. One of the most reliable options available is 1J75 alloy strip, manufactured under ASTM F35 standards. Known for its very high permeability and low coercivity, this alloy is indispensable in transformers, sensors, and precision instruments.
For more details, pls directly contact us.
1J75 is a nickel-iron soft magnetic alloy, containing approximately 75% nickel with the balance iron. This composition ensures high magnetic softness, meaning it can be easily magnetized and demagnetized without significant energy loss. Its permeability is much higher than conventional silicon steels, and its coercive force is extremely low, making it ideal for sensitive applications. With a density of about 8.7 g/cm³ and operating stability up to 500°C, it provides both precision and durability.
