UNITED STATES PATENT OFFICE.
FELIX vIsm'rAiNEn, or NEW YORK, N. Y.
/ ALLOY.
A particular object of the invention is to provide a new and improved alloy which is non-corroslve and W111 not rust, which lS acid-resistant, which will retain its luster and ability and which is of extreme hardness and one which is capable of withstanding great stresses and severe and sudden shocks.
A further object of the invention is to produce an alloy characterized by its great ture as well as one thatmay be used in the place of nickel plating which will take a high polish and retain the polish without the necessity of machining.
The alloy in its preferred composition consists of a mixture of the following ingredients in approximately the proportions specified, namely:
Per cent Copper 87.05
Aluminum 11.80 Iron 0.43 Silicon 0.49 Tin Although I prefer to make the improved alloy from the various ingredients in the proportions given above for the best results, not only asto the heat and acid resisting qualities of the alloy, its homogeneity of structure, and its reat compressive strength to withstand shocks, but also as to the adaptability of the alloy for casting and other forming operations, nevertheless, I have found that an alloy, satisfactory for the purposes of the invention andhaving substantially the qualities obtained by compounding'the ingredients inthe quantities hereinbefore referred to,-may be made from these various ingredients within the following limits 2-- 7' Per cent Copper about 85 to 89 Aluminum about 9 to 13 Iron about .25 to .65 Silicon about .30to .70
Tin a ut .07 to .12
Application filed June 2,
1926. Ser1al No. 113,334.
The ingredients are melted together to form the alloy which can be poured while molten into molds in which it is cast into the desired form. The resultant product is one of high color and brilliant luster and extreme hardness and the surfaces of the article formed therefrom may be polished in any well-known or preferred manner and, as the result of the polishing operation and without. the necessity of depositing any coating or plating thereon, the article has imparted thereto a high luster, which it will retain without tendency to tarnish.
The alloy is of extreme hardness and in laboratory tests using thefBrinnell method for hardness, the alloy is given a rating of 266 in the Brinnell hardness test.
For compression, a piece of the alloy measuring 1.003 x 0.991 inches having the height of 2.05 inches was subjected to a load of 100,000 pounds with the result that the distortion was found to be 1.015 inches by 0.995 inches or a distortion only measurable in the thousandths of an inch, which is not appreciable in test pieces of larger dimen- 7 sions. 1
It will therefore be noted that this alloy will stand an enormous pressure per square inch without breaking down or displaying evidences of brittleness, which is usually present in very hard metallic alloys.
It will be evident, therefore, that I have provided an improved alloy which is noncorrosive, rustproof, acid resistant and is of extreme hardness and also possesses as highly desirable properties and capable of many uses. It should be manifest that a considerable range in proportions of the various ingredients may be invoked within the scope of my invention as defined in the following claims.
What I claim is:
1. An alloy consisting of the following ingredients in substantially the proportions specified: copper 85 to 89%; aluminum 9 to 89%; aluminum 9 to 13%;.iron .25 to ingredients in substantially the proportions specified: copper 87 05%; aluminum 11.80%;
.65%; silicon .30 to .70%.
3. An alloy consisting of the following iron .43% and silicon 49%. ingredients in the proportions specified: In testimony whereof I affix my signs.- 5 copper 87.05%; aluminum 11.80%; iron 1111 8.
.43%; silicon .49%; and tin .10%.
4. An alloy consisting of the following FELIX VISINTAINER. [L. 5.]
