Description

UNITED STATES PATENT OFFICE.
EZECHIEL WEINTRAUB, OF LYNN, MASSACHUSETTS, ASSIGNOR T0 GENERAL ELECTRIC- COMPANY, A CORPORATION OF NEW YORK. I
PLATINUM ALLOY.
No Drawing.
To all whom, it may concern:
Be it known that I, EzEcHIEL \VEINTRAUB, a citizen of the United States, residing at Lynn, in the county of Essex, State of Massachusetts, have invented certain new and useful Improvementsin Platinum Alloys, of which the following is aspecification.
The present? invention comprises new and useful alloys of platinum and either tungsten or molybdenum, or of the three together, having the property of being malleable, resisting oxidation and having besides greater mechanical strength than platinum.
The new alloys embodying my invention comprise at least about twenty parts of platinum, the remainder being tungsten or molybdenum, or both. For the preparation of the alloys I prefer to use the metals in a ductile state. One mode of procedure is to use very thin wires of the respective metals, the wires being combined in proper proportions. The wires are twisted or braided intimately together and heated to the melting point in an inert environment, for example, by the heat of a mercury arc until alloying takes place. Vapor arc furnaces suitable for melting the metals in contact with one another are shown in my Patents Nos. 997,882 and 1,068,615. The alloys thus prepared re- Specification of Letters Patent.
Application filed March 5, 1914. Serial No. 822,596.
Patented May 12, 1914.
semble platinum in appearance, but in tensile strength and hardness arev superior to platinum. The permanency in air and good wearing properties of these new alloys constitute properties making the alloys superior to platinum and iridium for many purposes,
particularly for scientific instruments, jewelry, electrical contacts, and the like.
\Vhile the appended claims refer specifically to tungsten, I wish to claim thereby also the platinum alloys of molybdenum.
Vhat I claim as new and desire to secure by Letters Patent of the United States, is 2-- 1. A malleable alloy which is permanent in air comprising tungsten and platinum, the latter constituting at least about 20% of the alloy.
2. A malleable alloy comprising about 20 to 60 parts of platinum and about 80 to 40 parts of tungsten, said alloy being characterized by permanence in air and by being more refractory and harder than platinum.
In witness whereof, I have hereunto set my hand this 2nd. day of March 1914.
