Description

.SI T AIENTmm 1 WALTERRUBEQ, or- BERLIN, GERMANY.
To all whom it may concern: 1 Y
Be it known that I, \VAL'mnRiinnL, a subject' of the Emperor of Germany, residing at Berlin, in the Empire of Germany, have invented a new' and useful-Method of Producing Metal Alloys and a Compound for the Production Thereof.
The present invention. relates to a new method of producing metal alloys-especially those composed chiefly of copper and zinc-containing elements of those metals such as chromium, manganese, tungsten and vanadium which has less affinity for chlorin than zinc has at thefusing temperature of the chlorid of such metal. Such alloys are of high technical value and may be produced by this method at a relatively low cost.
The invention also relates b0 a compound to be used in theproduction of alloys of the character referred to.' At the present time much difl iculty is experienced, in the pro duction of such alloys; andto alloy such metals as chromium, manganese, tungsten or vanadium with copper and zinc, has been found very ditlicultr In carrying out my invention I first form a compound of the articular metal with zlnc and then melt t e alloy thus formed with the copper or other metal.
The first compound is obtained by melting a chlorid of the particular metal with a proper proportion of zinc. For example, to produce an alloy containing chromium, chromium chlorid in the proper proportion to produce the desired percentage of chromium in the final alloy is melted with zinc and the chromium liberated is alloyed in a nascent state with the zinc present in excess; The chromium-zinc compound thus produced is melted with an amount of copper .or other metal proportional to the percentage of chromium desired. For example, to reduce 100 kgs; of chromium-bronze 3.2 gs. of chromium chlorid may be alloyed with 40 kgs. of zinc. The chromium-zinc compound thus obtained is added to 57 kgs. of copper.
l or a mangancsebronze 2.5 kgs. of man anose chlorid (MnCl. may be melted with.
' the zinc and this compound may be added to a propm-tionate amount of copper. The particular proportions may, however, be varied within wide limits according to the desired percentage of the chromium or manganese desired in the final alloy. Thus to produce four per cent. of chromium of manganese in the bronze the chromium chlorld would be I specification o t Letters Patent. Patented July 12, l 910.

increased to 10 kgs. and the manganese chlorid to-'l2.8 kgs. These amounts it will he understood are for producinglOO kgs. of the final zinc-copper alloy.
Under this process chlorids may be added up to five per'cent. of the metal containing the chlorid without requiring heating above the melting point of the copper.
An alloy produced by this process and containing one per cent. of chromium or manganese, hfty eight parts of copper and forty parts of zinc has a strength of fifty eight kilos. with a limit of elasticity of twenty nine kilos. and,extensibility of from 18 to 20 per cent. An addition of about two per cent. of aluminum will greatly accelerate the reduction of the chlorids. 1n thus compounding the zinc with the ehlorids of the manganese, chromium, or other metal, chlorid of zinc is produced and this is of special advantage.
.In casting all alloys containing a certain quantity of zinc, oxid of zinc is produced and this forms accumulations and frequently produces loose, spongy places in the walls of the casting. The chlorid of zinc that is produced in my process dissolves this oxid of zinc, so thatmuchbetter castings are obtained.
As chlorids of chromium, manganese and tungsten are very inexpensive compared with the pure metals, the alloys containing these metals can be produced by my process at much less expense than has heretofore been possible. The alloys of chromium and manganese are especially important. They present great strength at ordinary temperatures,
and do not lose their strength when heated to a high temperature. 'lheehromiuln alloys also exhibit great resistance to chemical agents, because the chromium is reduced from a chlorid and is alloyed in state nascemlz' with the zinc; it is hardly attacked by such agents as sulfuric, nitric and hydrochloric acids. Copper'zinc alloys containing chromium and manganesewhen produced by rcsent methods do not have this power oi resistance to the action of chemicals, because the chromium or manganesc' reduced in accordance with the Goldschmidt process or with carbon (10 not possess any neutrality to acids.
