At DLX, we understand that precision and reliability start with material quality. Our 1J85 Nickel Alloy Bar represents the perfect combination of magnetic precision, thermal stability, and mechanical strength. This material has become one of our most trusted alloys for high-end industrial, aerospace, and energy applications.
1J85 is a nickel–iron Soft Magnetic Alloy with a carefully controlled composition. With roughly 45% nickel and the balance iron, it delivers high magnetic permeability and low coercivity, making it ideal for components that require accurate magnetic response and minimal signal interference.
One of its key advantages is its low thermal expansion coefficient, ensuring stable dimensions even under temperature fluctuations. This makes it perfect for sensitive instruments and mechanical assemblies where precision cannot be compromised.
