Product Introduction

In the world of precision instruments and electromagnetic devices, material selection can make all the difference. 1J85 alloy strip, designated ASTM F30, has emerged as a leading solution for applications that demand high magnetic performance combined with stability and reliability. At DLX, we specialize in providing 1J85 alloy strip that meets the stringent requirements of precision instrument manufacturers and electronic component designers.

For more details, pls directly  contact us.

1J85 is a nickel-iron soft magnetic alloy, typically consisting of around 81% nickel and 15% iron, with small additions of other elements to optimize magnetic properties. This composition grants it very high magnetic permeability, low coercive force, and a stable saturation flux density. These properties make 1J85 alloy strip ideal for precision instruments, including sensors, transformers, and other electromagnetic devices where low energy loss and high responsiveness are essential.

Our production process at DLX ensures uniform thickness, smooth surface finish, and consistent magnetic properties across the entire strip. Available in thicknesses from 0.01mm to 1.0mm, and customized widths and lengths, our 1J85 alloy strip can meet virtually any design requirement.
