ALUMINUM ALLOY.

No Drawing.

To all whom it may concern:

Be it known that l, WiL IAM' A. Md ADAMS, 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 useful Aluminum Alloy, of which the following is a specification.

My invention relates to an aluminum alloy, with the object in view of providing a silvery White metal capable of being rolled, hammered, machined and otherwise worked as a malleable metal for general use in the arts.

With the foregoing object in View, my invention consists of an alloy composed of tin, silver, cadmium and aluminum combined in substantially the following proportions, to wit: tin, eight per cent. by weight; silver four per cent. by weight; cadmium eight per cent. by weight; and aluminum eighty per cent. by weight. In combining these substances to form the alloy, 1 first melt a portion of the aluminum, for example one-third, and raise it to such atemperature that the silver, when introduced, will readily com bine with it. The silver is then introduced and after it has combined with this portion of the aluminum, the remainder of the aluminum is introduced into the mass, such in troduction materially lowering the temperature of the mass. The cadmium is then lll' troduced and then the tin, or the tin may be Specification of Letters Iatent.

of introduction of these two substances being; a matter of choice or convenience. It is to be understood that the mass is to be thor-- oughly agitated when the different elements are introduced in order to make the mass homogeneous and thoroughly min the solostance being introduced throughout the U'IHSS into which it is introduced. The mass is then skimmed to remove any flux which may have been employed and then it may be poured to form ingots of any desired shape. These ingots are of a malleable nature and may be treated as a malleable metal and will have a brightness substantially like that oft unoiiidized silver. This metal will retain its luster and is proof aga inst disintegration by It is extremely ductile and amply strong for the manufacture of all silverware and may be furnished at a cost far below the cost of silver.

What I claim is:

An aluminum allo com weed of tin silver, cadmium and aluminum in the or-open trons substantially as set forth.
