JUSTUS W. LEHR, F BALTIMORE, MARYLAND, ASSIGNOR, IBY MESNE ASSIGNMENTS, TO U. S. INDUSTRIAL ALCOHOL 00., A CORPORATION OF WEST VIRGINIA.
NICKEL-COPPER ALLOY.
,No Drawing.
To all whom it may concern:
Be it known thatI, JUSTUS W. LnHR, a
citizen of the United States, a resident of Baltimore,'State of Maryland, have invented a certain new and useful Nickel-Copper a reduction. A further-object is to provide a mix for an alloy which willnot contain large amounts of soft metals, such as tin or lead, which makethe product more fusible but uneven in texture and hardness, and difficult to work. A still further object is to provide a noncorrosive alloy for general use, which will have a high tensile strength and which may be made in the form of white metal at minimum expense, without the high cost due to scrap loss in prior practice. Further objects will a pear hereinafter.
The invention in ts preferred embodiment consists of an alloy comprising nickel to %,tin 2 lead 1 to 8%, andthegre- 47' mainder copper; no zinc in any substantial amount is added. A deoxidizer such as silicon, manganese, and zirconium may be used in an amount equal to 1% or less. The
. nickel percentage may range from 20 to.40%,
however, and the percentage of tin may rangefrom 1 to 6%, with corresponding alterations in the percentage of the copper. Such a mix when melted would produce a white metal alloy that has excellent tensile strength and that is eminently suited for making white metal articles that will resist corrosion, such as spigots, pipes, conduits,
valves, etc. In makin the mix Monel metal is preferably not use since it is desired to Application filed August 28,1923. Serial No. 659,841.
prepare the mix from the pure unalloyed metals and thereby avoid the presence of the small amounts of impurities and other metals naturally present in Monel metal and similar metals.
The metal may be cast by a special process. In casting in a permanent mold, .the temperature is controlled to permit a rapid cooling in order to freeze out a maximum concentration of the nickel rich constituent, whereby there will be obtained the advantages of a high nickelalloy While at the same time retaining the total nickel content at a comparatively low figure, so that the diflie culties' of melting the mix will be lessened. Casting in a permanent iron mold, dusted with graphite, will secure the results de' sired, and will produce closely joined solid solutions of high nickel and copper content respectively without the formation of intercrystalline materials.
The alloy produced from the above composition or compositions will possess great strength, uniformity, resistance to corrosion, and a close-grained structure. In these properties, it is equal to and even superior to the well-known Monel metal which has a substantially higher content of nickel.
As many apparently widely diiferent enibodiments of this invention may be made without departing from the spirit thereof, it is to be understood that I do not intend to limit myself to the specific embodiment thereof except as indicated in the appended claims.
I claim'z 1. A non-corrodibl'e alloy containing nickel 20 to 40%, tin 1 to 6%, lead 1 to 8%, the remainder copper, and containing no zinc.
2. A non-corrodible alloy containing nickel 20% to 40%, tin in a substantial amount not exceeding 6%, lead in a substantial amount not exceeding 8%, and over copper.
3. A non-corrodible alloy containing nickel 20% to 40%, tin in a substantial amount not exceeding 6%, lead in a subm memee sta ntial amount not exceeding 8%, ever 45%- tainingnickel 25150 40%, tin 1 to 6%, lead 10 of copper and substantially no zmc. 1 to 8%, and the remainder copper.
4. A. non-corrodible alloy containing 7. A deoxidized non-corrodible alloy connickel 25 to 45%, tin about 2 lead 1 to mining nickel 35 to 40%, tin about 2 5 8%, and the remainder copper. lead 1 to 8%, and the remainder copper.
5. A non-corrodible alloy containing In testimony that I claim the foregoing, 15 nickel ever 25%, tin about 2 lead 1 to I have hereunto set my hand this 7th day 8%, and the remainder copper. of August, 1923.
