Product Description
1J85 (soft magnetic alloy-permalloy)
(Similar grades: Ni80Mo5, E11c, permalloy, 79HMA, PCS)
1J85 Permalloy refers to an iron-nickel alloy with a wide range of nickel content, ranging from 35% to 90%. The biggest feature of Permalloy is its high magnetic permeability in weak magnetic fields. Their saturation magnetic induction intensity is generally between 0.6-1.0T.
In 1913, American GWElmen discovered that Ni-Fe alloys with a nickel content of 30% to 90% have good soft magnetic properties under weak and medium magnetic fields. Among them, nickel-iron alloys containing 78% nickel The initial permeability μi was the highest, so it was named permalloy, which means magnetically permeable alloy. He also discovered a special heat treatment process to further increase the initial permeability of the Ni-Fe alloy by 50% to 90%, called "permalloy heat treatment". In 1921, 78% Ni-Fe alloy was used in telephone relays. In 1924, the British Smith (Smith) and others invented a 76% Ni-Fe alloy with copper and chromium, called "Mumetal" (produced by the British Telcon company). In 1931, the American T.D. Yensen invented the process of vacuum melting and hydrogen high temperature annealing to purify the alloy, and developed the super nickel-iron alloy under the brand name Hipernik. In 1934, American G.A. Kelsall discovered that magnetic field heat treatment can significantly increase the maximum permeability of iron-nickel alloys. After 65% Ni-Fe (65 permalloy) heat treatment in a magnetic field, μmax is increased by about 10 times. In 1947, American R.M.Bozorth and others invented the alloy with the highest μi and μm, called superpermalloy. In the early 1960s, the China Iron and Steel Research Institute invented a method of treating with a transverse magnetic field and adding an appropriate amount of oxygen to obtain a 65% Ni-Fe alloy (Chinese brand 1J66) with Br and Hc close to zero and a very constant magnetic permeability. After the 1970s, in order to meet the needs of the development of high-frequency switching power supplies and magnetic recording technology, various elements such as niobium, tantalum, vanadium, tungsten, titanium, silicon, and aluminum were added to nickel-iron alloys containing high nickel to obtain high hardness and high hardness. The resistivity, low loss, high permeability alloy has become the most representative alloy in soft magnetic alloys with the most types of properties, the widest variety and applications.
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. It is mainly used for high-conductivity magnetic yoke irons, sensitive relays, low-loss micro-motors, low-power power transformers, pulse transformers, transistor switches, magnetic amplifier magnetic modulators, sensitive signal input and output transformers, magnetic sensors for 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.
