Description
ROBERT ABBOTT HADFIELD, OF SHEFFIELD, ENGLAND.
' MAGNETIC ALLOY.
' No. s42,4o3.
Specification of Letters Patent. Application filed November 8, 1906. Serial No; 342,469.
Patented JanL29, 1907.
T0 at whom it may concern.-
Be it known-that I, ROBERT ABBOTT HAD- FIELD, a subject of the King of Great Britain, residing at Parkhead, Sheffield, England, have invented a certain new and useful Improvement in Magnetic Alloys, of which the ollowing is a specification. g
The invention is an alloy having magnetic and electric properties especially adapting it for use in ballast-coils, transformer-plates,
and like electrical apparatus, wherein it is of great imdportance to reduce the total ma netic an' electriclosses to the lowest possib e de'reef 0 ploduce my said alloy, I take pure Swedis or other suitable ure iron and melt this together with silicon om two to 4.5 per cent. of the entire mass, manganese not exceeding .7, and aluminium not exceeding 1.3 per cent. I may effect this melting by a crucible process or instead thereof produce decarbonized or desiliconized iron by any steel-making processsucl 1 as the. openhearth, the pneumatic, or the electrical process-adding to such iron the desired percentages of silicon, aluminium, and manganese.
It is important to keep the percentage of'carbon present low-say under about .12 per cent. As one specifio'example of my said alloy I give the following percentages:v silicon 3.98, manganese .08, Ialuminium,.95, with iron, and, in this particular case, carbon .08. obviously low.
Another example in which the manganese is relatively high is silicon 3.57, manganese .67, aluminium .1, with iron, and, this particular case, carbon .09. I claim An iron-silicon-manganese-aluminium alloy containing silicon from two to 4.5 per Here the manganese is cent, manganese not exceeding .7 per cent.
and aluminium not exceeding 1.3 per cent.
In testimony whereof I have affixed my signature in presence of two witnesses.
ROBERT ABBOTT HADFIELD.
Witnesses:
EUSTAOE H. BARKER, JOHN J. NEWPORT.
