Description
. sitions and Alloys for the UNITED STATLET OFFICE WALTER ROBEL, OF VIENNA AUSTRIA-HUNGARY.
METHOD .OF PRODUCING COPPER-ZINC COMPOSITIONS AND ALLOY FORTHE PRODUC- TION THEREOF.
No Drawing.
' Specification of Letters Patent.
Application filed July 9, 1909. Serial No. 506,783.
To all whom it may concern:
die it known that I, WALTER RtinEL, a citizen of the Empir of Germany, residing at- Vienna, in the Empire'of Austria-Hun gary, have invented a new and useful Method of Producing Co per-Zinc Comporoduction Thereof. of which the following is a specification.
Heretofore copper-zinc compositions have been produced by melting with copper and zinc a small quantity of alloy consisting of copper. iron, nickel and aluminum. The composition. so produced possesses valuable properties, but it is not snitable for many pnrwses because of its low density, which rem crs it permeable to water under very high pressure. Such brass can be satisfactorily cast in bars, but itis not practicable to produce satisfactory castings for delicate working pieces and bodies, such as are required in valves and the like.
This invention relates to an improvement in the method of producing copper-zinc compositions and in the alloy used for the purpose by which these defects are overcome.
In carrying out my. invention I employ an alloy which contains, in addition to the copper, iron and aluminum, a quantity of manganese, either with orwithout nickel. The manganese increases the tensile strength and the elastic limit. When nickel is used, it is in a considerably increascdpercentage and raises the limit of elasticity. In case where a greater tensile strength and a higher limit of elasticity are required, both manganese and an increased percentage of nickel are employed. If higher tensile strength and high elastic limit are required, the
. nickel may be omitted and the percentage of manganese may be increased. When nickel is employed the alloy consists of 2 atomic weights of copper, 2 atomic weights of iron, 3 atomic weights of nickel, 1 atomic weight of manganese and 1 atomic weight of aluminum. These may be melted together in any known way. When nickel is omitted the percentage of manganese 1s mcreased to 3 atomic weights. The two alloys W111 thus correspond to the following formulae:
(1 Gu Fe Ni MnAl; (2 cu F-e Mn Al.
Thcmanganosc may be added to the composition in the form of ferromanganese, but
added to the copper and zinc: For example,
rammed Mar. 22, 1910.
a composition. according to my invention,
may consist of: 10 arts by weight of-thc alloy, 50 parts by weight of copper, 40 parts by weight of zinc, all being alloyed together n the usual known way.-
The relative proportions of the copper and zinc forming the composition body'to which the alloy is added may be varied.
The composition produced by this method possesses a tensile strength up to 60 kilograms per square millimeter. I
What I claim is: p
1. The method of producing copper-zinc compositions of increased tensile strength and elastic limit which consists in adding to a mixture of copper and zinc, an alloy containing co per, iron, manganese and aluminum in su sta'ntially the proportions ecified to an amount up to ten per cent. d? the whole mix.
2.-The method of producing copper-zinc compositions of increased tensile strength and elastic limit which consists in adding to a mixture of copper and zinc, an alloy consistin of copper, iron, manganese, nickel and uminum in substantially the propertions specified to an amount up to ten per cent. 0 the total mix.
3.-The alloy for increasing the tensile strength and elastic limit of copper-zinc compositions which contains two atomic weight of copper, two atomic weights of iron, three atomic weights of manganese and one part of aluminum. 0
4. The alloyfor increasing the tensile strength and elastic limit of copper-zinc compositions which consists of two atomic weights ofcop er, two atomic weights of iron, three atom1c weights of nickel, and one atomic weight each of manganese and aluminum.
I WALTER RllBEL.
