Lork Ni80mo5 / Mumetal / Hymu80 Permalloy Superalloy Strip for Shielding Material High Initial Permeability 1j85 Precision Alloy Coil

Product Description

Product Description

 

Introduction

LORK is a alloy manufacturer with 20 years of manufacturing experience.
 

1J85 alloy is smelted in a vacuum induction furnace. After being cast into a steel ingot, it is hot forged into a slab, then after hot rolling, pickling, and surface finishing, it is cold rolled into a finished strip or forged into the required bar. Most of these alloys are said to be used under alternating magnetic fields. They are mainly used for high-conductivity yoke irons, sensitive relays, low-loss micromotors, low-power power transformers, pulse transformers, transistor switches, magnetic amplifiers, magnetic modulators, and sensitive signals. Input and output transformers, magnetic sensors of aviation magnetic heading instruments, magnetic sensitive components in magnetic measuring instruments, moving and stators in precision electric meters, magnetic shielding and magnetic temperature compensation components.

1j85 Precision Alloy Applications

1J50 magnetic alloy, a Ni-Fe soft magnetic alloy, mainly applies to high magnetic conductivity yoke iron, sensitive relay, low loss micromotor, low power transformer, pulse transformer, transistor switch, magnetic amplifier, magnetic modulator, sensitive signal input and output transformer, magnetic sensor of aviation magnetic heading instrument, magnetic sensitive element of magnetic measuring instrument, stator and movable plate of precision electric meter, magnetic shielding and magnetic temperature compensating elements.
