Description
HENRYC. KIRK, OF ROLAND PARK, MARYLAND.
anu'mntvm ALLOY.
No Drawing.
To all "whom it may concern.
Be it known that I, HENRY C. KIRK, a citizen of the United States of'America, residing at Roland Park, Baltimore county, Maryland, have invented certain new and useful Improvements in Aluminum Alloys, of which the following is a specification.
This invention relates to an alloy of low specific gravity and high tensile strength. It is produced by alloy ing Monel metal with aluminum in the proportions of 90% to 97% aluminum with l0/; to 3% monel, or, as a' substitute for monel a corresponding amount of nickel and copper, two parts nickel to one part copper may be used. As a rule monel contains, probably as impurities, small quantities of manganese and iron. In testing the liereiiulescribed alloy, it is found that the presence of these so-called impurities gives a slightly improved result. particularly as to tensile strength.
An alloy consisting of 94% aluminum and 0% monel, when tested in the form of sand castings. is found to have a. tensile strength of from 19.000 to 22,080 pounds, with an elongation in two inches of from 3.; to 3%, its specific gravity being approximately 2.69.
Cast in iron molds the tensile strength of the same. alloy is from 25,140 to 25,310 pounds with an elongation in two inches of from 0} to 5%. specific gravity being 2.70 to 2.72. Both alloys roll, draw or spin to the best advantage and make a very sharp casting.
The metal which is the product of the invention bends without breaking through an arc of 45 over a mandrel the diameter of which is one half that of the test piece.
The product can be rolled and Worked Specificatimi of Iietters Patent. Application filed August 27,4918.
Patented June 3, i 919..
Serial No. 251,657.
with very few annealings, and when rolled in a sen'ii-hard condition, shows a tensile strength of 38,970 pounds. .Vhen annealed or in a semi-soft condition, the rolled metal has tensile strength of 27,200 pounds. In rolling the metal tested was reduced from a. thickness of inch to .030 inch.
This material makes stron drop torgings and is more ductile than with higher percentage of monel. and is less affected by salt water and climatic changes than other alloys of alumiinnn. Also uniformity of castings and consistent performance can be maintained with the usual foundry practice, 5. c., the metal is not as sensitive in point of strength to variations of melting point temperature as are the ordinary Zine,v aluminum and copper alloys.
Having thus described my invention. what 1 claim and desire to secure by Letters l atcut is:
'1. An alloy consisting of 90% to 07% aluminum. the remaining 10% to 3% including about two parts nickel to one part copper.
2. An alloy consisting of from 90% to 97% aluminum, the remainder including nickel and copper in the proportions of two to one and traces of manganese and iron.
3. An alloy consisting of ll-f1 aluminum, the remaining 6?. consisting principally of nickel and copper in the proportion of two to one.
