- for making sheets are improved by adding to it copper. in various quantities. In America, an alloy havlng about 8% copper is very extensively used for making castings for the automobile industry and for similar purposes. On the other hand, 2% to 5% copper is frequently added for making sheets, whereby the strength is materially increased. 7
Further, in the metallurgy of aluminum and its alloys, it has heretofore been universally held that a greater percentage of iron than that contained in ordinary commercial aluminum has a prejudicial effect. According to Schiermeister (Stahl & Eisen, page 87 1) ironaluminum alloys will hardly acquire technical importance.- According to Zeerleder (Metall & Erz 1917, page 330), iron has an injurious influence on the strength of aluminum and its alloys, and the percentage of iron must therefore be kept as low as possible. of the United States of America confirms these statements in its Circular No. 76.
An aluminum alloy according to this invention contains both copper and iron, the iron content exceeding one and one-half per centum of the alloy, and amounting, in some mixtures, to even four per centum 1%) thereof, and the alloy containing approximately twice as much copperas it does iron. Contrary to expectations, this alloy is particularly valuable owin to its strength, and is especially suitable or making cast- The Bureau of Standards Application filed February 10, 1922. Serial No. 535,655.
ings. An alloy with 1.75 %2.75% iron with -3.5%4.5% copper is particularly advantageous. For example, sand casting with 20% iron and 3.7% copper have been found to have a tensile strength of 19 kg. per sq. 5
mm. and 5% extension, a result not obtainable with other alloys of about the same specific weight, andnot even with chill mould castings.
The new alloy. can be advantageously rolled and drawn, and strengths of 38 kg. per
sq m m; and upwards can be obtained. That it is possible to obtain such a strength by employing admixtures that can be obtained readily and at a low cost, is of great importance commercially in connection with the use of the alloy. It is to be understood that the alloy may also contain the usual means for further improving its physical properties,
such as, for example, an admixture of man- 6 ganese, nickel, titanium, num, magnesium, cerium, the equivalents of these metals, in quantities of 0.1% to 2% of the total, and in addition,
wolfram, molybdeits quality can be improved by heat treatment.
I claim:
1. An aluminum-copper-iron alloy consisting of from 88% to 95% aluminum, the remaining per and iron in the relative proportions of two parts of copper to one part of iron, approximately.
2. An 'aluminum-copper-iron alloy consistim of from 92.75% to 94.75% aluminum 8C the remaining 7.25% to 5.25% being made up of copper and iron, in the relative proportions of 2.75% to 1.75% iron, to 41.5% to 3.5% copper.
In testimony whereof, I attixmy signature 85 in the presence of two witnesses.
