Description
Patented Mar. 22, 1932 UNITED STATES eAram" oFr-"ics CHARLES D. RUSSELL, 0F SHEBOYGAN, -WISCONSIN, ASSIGNOR '10 BUSEIIIITE CORPO- RATION, OF MILWAUKEE, WISCONSIN, A CORPORATIQN OF WISCONSIN ALUMINUM ALLOY No Drawing.
This invention relates to improvements in aluminum alloys and method. of producing the same.
It is one of the objects of this invention to provide an improved alloy which possesses the desirable characteristics of high tensile strength, tenacity, and ductility, and Which may be cast or worked with or without the necessity of additional heat treatment'to bring out the above mentioned properties.
A further object of this invention is to provide an improved aluminum alloy which may be readily polished and which is resistant to corrosion. v
A further object of this invention is to provide an improved alloy which, when cast,- can be bent and twisted while cold.
lVith the above and other objects in view, the invention consists of the improved aluminum alloy and method of producing the same, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.
The improved alloy comprises a major portion of aluminum together with copper,
chromium, and molybdenum. A small percentage of titanium may also be employed, and in the final product a small amount of iron is present in the form of an impurity. The following tabulation discloses the preferred ingredients together with the preferred range of proportions for each of said ingredients.
Aluminum 85-96% Copper -l 340% Chromium O. 7 5- 5% Molybdenumufi O. 10- 5% Titanium O. 05- 1% Iron (a small amount present as an impurity) In forming the alloy, the aluminum is melted to a bright red heat.
Application filed April 25, 1930. Serial no. 447,432.
sults, the alloy is first pigged and then remelted.
"By utilizing the above method, and the ingredients reci ed in the range of proportions set forth in the formula, an aluminum alloy is formed which is of great tensile strength and which possesses unusual ductility. The alloy can be employed for castings of all kinds, for extruding, and for drawing, rolling'and forging.
What I claim is:
1. An aluminum alloy comprising a major portion of aluminum together with 23-10% copper, O.755% chromium, and (HO-5% molybdenum, said alloy possessinghigh tensile strength, tenacity, and ductility.
2. An aluminum alloy consisting of a major portion of aluminum together with 340% copper, 0.755% chromium, 0.10-5% molybdenum, and 0.054% titanium, said alloy possessing high tensile strength, tenacity, and ductility.
3. An aluminum alloy com rising 85-96% aluminum, 23-10% copper, 0. 55% chromium, and 0.105% molybdenum, said alloy possessing high tensile strength, tenacity and ductility.
. 4. An aluminum alloy consistingof 85-96% aluminum, 340% copper, 0.755% chromium, 0.10 5% molybdenum, and 0.051% titanium, said alloy possessing high tensile strength, tenacity, and ductility.
5. An aluminum alloy comprising approximately 90% aluminum, 6% copper, 2% chromium, and 1% molybdenum, said alloy possessing high tensile strength, tenacity, and ductility. I
In testimony whereof I ailix my si ature.
