Specification of Letters Patent.
Patented June a, aura.
To all whom it may concern:
Be it known that l, WILLIAM A. Moi linens, a citizen of the United States, and resident of Bay Shore, in the county of Suffolk and State of New York, have invented a new and usefulAluminum Alloy, of which the following is a specification.
Myinve'ntion relates to an aluminum alloy with the object in View of providing an of aluminum, five parts by weight of copper and two parts by weight of silver.
In making the alloy, the aluminum is preferably first melted and the copper and silver introduced into the {melted aluminum and the mass raised to such a degree as to melt the copper and silver, the melted mass being thoroughly agitated to bring the molecules of the difierent elements into intimate contact. lhe mass is then allowed to cool, and may then be rolled or tooled as may be desired. l/Vhen rolled into a thin sheet, the alloy will present a brilliant white surface which will. not tarnish; the sheet may be bent at pleasure, and will'be so stiil and hard and at the same time resilient that the metal will keep the form into which it is bent without liability of becoming mashed out of shape. The small proportion of silver relative to the amount of copper and the small proportion of both silver and copper relative to the amount of aluminum makes the alloy almost as light as aluminum itself and adds but little to the cost of thealloy over the cost of aluminum alone.
I am aware that the elements, aluminum, copper and silver have heretofore been combined to form an alloy in which the silver exceeded the copper, but I believe that I am the first to succeed in producing a nontarnishable, tough, resilient and stiff alloy capable of being rolled and worked like silver or copper by using an amount of silver so relatively small as compared with the amount of copper and aluminum.
hat I claim is An aluminum alloy composed of aluminum, copper and silver combined substantially in the proportions of one hundred parts aluminum, five parts copper and two parts silver.
In testimony that I claim therforegoing as my invention, I have signed my name in presence of two witnesses, this twenty-third day of January, 1913. WILLIAM A. McADAlilS.
. Witnesses l Gnonon BARRY, HE RY C. 'llriinirn.
