Description
Patented Mar, 22, 1932 UNE'FEQ STATES PATENT OFFECE CHARLES D. RUSSELL, E SHE BOYGAN, WISCONSIN, ASSIGNOR, TO RUSELITE CORPORA- TIUN, 0F MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN I ART OF METALLURGY N o Drawing.
This invention relates to improvements in the art of metallurgy, and more specifically to an alloy and mode 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 objectof this invention is to provide an improved alloy which may be readily polished and which is resistant to corrosion.
A further object of this invention is to provide an improved alloy, which, when cast, can be bent and twisted while cold.
A further object of this invention is to provide an improved alloy which possesses a high electrical resistance.
A. further object of this invention is to produce an alloy which is particularly adapted for use in highly stressable springs or the like.
l-Vith the above and other objects in view, the invention consists of the improved alloy and mode of producing the same, and all its parts and combinations, as set forth in the claims, and all equivalents thereof.
The improved alloy, in its preferred form, comprises a major portion of copper, together with aluminum, molybdenum andtantalum, the molybdenum serving as a strengthener and the tantalum serving to render the alloy resistant to corrosion and of high electrical resistance. In some instances, other corrosion resistant material such as chromium may be substituted for tantalum. The following tabulation discloses one combination of ingredients to ether with a desirable range of proportions or each of said ingredients.
, Per cent Copper 85 Aluminum 3 -12 Molybdenum 5 Tantalum .10 3
In forming the alloy, the copper and aluminum may be mixed together and heated to a temperature of approximately 2800 degrees I like.
Application filed July 21, 1930. Serial No. 469,640.
Fahrenheit, a suitable flux being utilized. Next molybdenum and tantalum may be add ed together, and the resulting mixture may be reduced in to minutes. The molten mass is kept at a bright red heat at all times and is stirred well before being poured into molds.
By utilizing the above method, and the ingredients recited in the range of proportions set forth in the formula, a bronze alloy is formed which is of exceptionally high tensile strength and which possesses unusual ductility for an alloy of such strength. The material produced is also extremely resistant to corrosion and is therefore capable of advantageous use for many purposes, such as for steam turbine blading, springs, and the The alloy can be employed for castmgs of all kinds, and for drawing, rolling and forging.
What I claim is:
' 1. An alloy comprising a major portion of copper together with 312% aluminum, .105% molybdenum, and .10-3% tantalum, said alloy possessing high tensile strength,
tenacity, and ductility.
2. An alloy comprising approximately 90% copper, 7% aluminum, 2% molybdenum, and 1% tantalum, said alloy possessing high tensile strength, tenacity, and ductility.
3. An alloy comprising a major portion of copper together with 342% aluminum, .105% molybdenum, and .103% of one of the corrosion resisting metallic elements tantalum and chromium, said alloy possessing high tensile strength, tenacity, and ductility.
In testimony whereof I aflix my signature.
CHARLES D. RUSSELL.
