Patented Dec. 29, 1931 0f the alloys in the l0 UNITED s'rn'ras PATENT OFFICE SYDNEY IBECKINSALE, OF BELVEDERE, KENT, ENGLAND MAGNETIC ALLOY No Drawing. Application-filed July 8, 1931, Serial No. 549,569, and in Great Britain July 14, 1930.
This. invention relates to magnetic materials formed of alloys in which the principal constituents are nickel and iron. In accordance with this invention we form such analloy of nickel, iron, silver and manganese. Copper and silicon a ents of the alloy. The addition of manganese I with silver improves the working properties process to which they are subjected during the manufacture of wire, strip or powder. In addition proved working properties the manganese acts as a deoxidizer. I
The silicon can be omitted or the constituents, manganese and silicon, can be used together in dependence upon the properties required for the alloys.
' tion of wire The constituents of the alloys may be in the following range of proportions Nickel from 25% to 80% Iron from 15% to Silver from about .05% to 10% Copper up to 10% Manganese from about .1 to- 10% -These alloys have a high permeability which makes them suitable for use on telephone cable transmission, and the more duo tile of the alloys are suitable for being used in the form of wires and tapes as well as pow-.
der for pupin coils.
These alloys are in two series: (a) those low in silver and suitable for the producand strip by hot working processes, (6) those with silver contents exceeding 0.5% and, particularly suitable for the production of powder by a pulverizing process.
An alloy which has been found suitable for This" alloy may also be made into dust by processes other than pulverizing.
may also form constitu-' to giving im-- Typical alloys for the production of powder by a pulverizing process are the following:-

Nlckelfi 37.5 Iron 1 57 Copper 1 Manganese -1. 0.5 Silver 3 Silicon 1 The permeability of the alloys may be improved by heat treatment consisting of annealing at 900 0. followed by slow cooling. What I claim as myinvention and desire a to secure by Letters Patent is 1. High permeability -magnetic' alloys comprising nickel, iron, silver and manganese.
2. High permeability magnetic alloys comprising nickel, iron, silver, manganese and copper.
3. A high permeability magnetic alloy having constituents in the following range of proportions Nickel from 25% to 80% Iron from 15% to 60% Silver from about .05% to 10% Copper u to 10% anganese from about .1; to 10% 4. A high permeability magnetic alloy,

5. A high permeability magnetic alloy,
suitable for the production of powder by a pulverizing process, halving the following composition Percent Nickel opper Manganese 0.75 Silver 2.0 Silicon- 0.2
6. A high permeability magnetic alloy,
Suitable for the production of powder by a pulverizing process, having the followmg composition Per cent Nickel Iron 57 Copper .1 Manganese 0.5 Silver 3 Silicon f 1 In testimony whereof I aflix my signature.
