1J75 is a high-nickel Soft Magnetic Alloy primarily composed of approximately 75% nickel and 25% iron. This balanced composition gives the alloy exceptional magnetic permeability and low coercive force, making it ideal for electromagnetic components that demand high sensitivity and efficiency. Compared to cobalt-iron or lower-nickel alloys, 1J75 stands out for its stable magnetic properties, excellent corrosion resistance, and consistent performance across a wide temperature range.
The alloy is known for its smooth magnetization curve and low hysteresis loss, which means it responds efficiently to magnetic fields with minimal energy loss. 1J75 also maintains good mechanical strength and workability, allowing it to be machined or formed into precise shapes for electrical and mechanical components.
