ALLOY.
Specification of Letters Patent. Pa,tented Apr. 27, 1920.
Divided and this application flied December 11, 1918. Serial No. 266,328.
To all whom it ma" concern:
Be it known that I, Fos'rnR MILLIKEN, a citizen of the United States, and a resident of Lawrence, in the county of Nassau and State of New York,'have invented a new a new and improved alloy characterized by having a high acid resistmg quality, an in creased density, an exceedingly close and fine grain, great tensile strength, increased elasticity, and electrical resistance.
The alloy is formed of copper, nickel, iron and zinc under the influence of chromium.
In carrying out the invention use ismade of copper, 50 to 60 per cent; nickel, 26 to 34per cent; iron, 4 to 8 per. cent; zinc, 7 to 11 per cent.; and chromium, .25 to 5 per cent.
The metal in each case consists of one hundred ounces of the four metals and the percentage of chromium is then added extra. A large percentage of chromium after the latter has done the work of purifying the alloy, passes off in the slag, and the remaining small percentage of chromium forms a component part of the alloy. Ad-
ding the chromium to the previously formed I alloy of copper, nickel, iron and zinc permits of using a comparatively small amount of chromium for the purpose of purifying the alloy. 1
It is understood that the addition of chromium has the double function of purifying the copper, nickel, iron and zinc and of adding a valuable ingredient to the alloy Specimens of, the alloy tested for three months in the acid test disclosed, with the alloy formed under the influence of chromium, a loss of .0079 to .0117 per square inch and hence it is manifest that an alloy of the character specified has high acid resisting properties. It has also been found that an alloy produced under the influence of chromium has increased density and the grain is closer and finer and resistance to corrosion is increased.
It is expressly understood that the deoxidizing agent removes an oxidized portions that may have formed on an one of the metals forming the alloy and ence no cavities; fissures, recesses or the like and incident to oxidation are formed in the alloy. The alloy is thus compacted and its elastic limit and tensile strength are considerably increased relative to any alloy formed of the same metals without the influence of the deoxidizing agent. It is well known that when a metal is deoxidized and is free of cavities and the like its electrical resistance is increased and this is expressly thecase in the present alloy. It has been found that the alloy as described and having the addition of a trace of chromium has a tensile strength of approximately 89,600 lbs. with an elastic limit of over 60% of the tensile strength.
Having thus described my invention, I claim as new and desire to secure by Letters Patent An alloy consisting of the following ingredients in about the following proportions, copper50 to 60 per cent., nickel 26 to 34 per cent., iron 4 to 8 per cent., zinc 7 to 11 per cent., the said copper, nickel, iron and zinc being in a deoxidized state, and chrom-
