QUARTERNARY -ALLOY SPECIFICATION forming part of Letters Patent No. 533,970, dated February 12, 189 5.

Application filed November 16, 1 8 94.

To all whom it may concern:

Be it known that we, PAUL FRANQOIS 'DE SUSINI and EUGENE AUGUSTE LEON LANG- great mechanical resistance to tension, shock and compression; also by its beautiful golden color and by its superior ino'xidizability. It moreover, is capable of being rolled with the I utmost facility, either cold'or hot, to all thick- It may be molded with ease to'great thinness without presenting blowholes in sand, metal or other molds. Having great resistance and ahigh ductility it may be extended to capillary diameters. It may be forged like iron with facility and may,there-' fore be adapted to the'manufacture of most delicate and complicated objects. Its malleability, ductility and elastioityare those of metals possessing these qualities in the highest degree. It may be drawn out in tubes of all diameters and thicknesses, either hot or cold, and may be stamped or embossed, for any mechanical or artistic purpose like gold, silver, copper, brass, &c. According to its degree of hammer hardening or annealing it may be elongated to from three to forty per cent.

This new quarternary alloy possesses elasticity and resistance equal to those of the best steels, together with ductility, malleability elongation equal to those of copper, brass, gold and, silver. Owing to these properties it may with advantage take the place of all the metals usually employed in most of the industrial applications beginning with steel and iron, including copper, brass, bronze and ineluding also most precious metals and their alloys.

The new alloy is composed of copper, aluminium, tungsten and phosphorus. Thecomposition being always the same it may, nev- Serial No. 29,042. (No specimens.)

ertheless, vary according to the quantities of the several component bodies, such variations depending upon the degree of resistance to elongation, ductility and malleability sought to be obtained to answer the purposes for which it is-intended and which allows of the production of metals according to a scale of numbers corresponding to the most varieduses'.

We have found that by varying the composition, quantitatively, the following eight fundamental types may be obtained:

First, copper, ninety per cent.; aluminium, five per cent.; tungsten, four and one-half per cent.; phosphorus, one-half per cent.

Second, copper, eighty-nine per cent.; aluminium, six per cent.; tungsten, four and onehalf per cent.; phosph0rus,-one-half per cent.

Third, copper, eighty-eight per cent.; aluminium, seven per cent.; tungsten, four and one-half per cent.; phosphorus, one-half per cent.

Fourth, copper, eighty-seven per cent. aluminium, eight per cent.; tungsten, four and one-half per cent.; phosphorus one-half per cent.

Fifth, copper, eighty-six per cent.; aluminium, eight per cent.; tungsten, five and onehalf per cent.; phosphorus, one-half per cent.

Sixth, copper, eighty-five per cent.; aluminium, nine per cent.; tungsten, five and one-half per cent. phosphorus, one-half per cent.

Seventh, copper, eightythree per cent.; aluminium, ten per cent. tungsten, six and one-half per cent.; phosphorus, one-half per cent.

Eighth, copper, ninety-five per cent.; aluminium, three per cent.; tungsten, one and one-half per cent.; phosphorus, one-half per cent.

We proceed in the manner as follows: First, the first operation consists in combining the tungsten with copper. employing pure metallic tungsten, which is very costly and difficult to obtain, we resort to the direct reduction of tungstiferous ore by electrolytic copper, chemically pure, in the presence of carbon (charcoal) in a brasque crucible highly treated in a crucible furnace. We then obtain a metallic mass containing fifty per cent. of copper and fifty per cent. of tungsten, alloyed with traces of other metals which happened to be in the ore, which how ever, do not injure the composition. Second, the alloy thus obtained is put in a crucible with a quantity of copper necessary to produce with it one of the eight above mentioned compositions Third, when the compound is melted at white-red heat and intimately mixed, we add the quantity of aluminium indicated in the formula. Fourth, the aluminium melts immediately. The mass is then given another good stirring and finally to it is added onehalf of a per centum of phosphorus which refines it, frees it from all impurities which will gather on the surface of the bath, whence it may be removed and poured at cherry heat into sand or other suitable ingot molds. The unmolding may be effected immediately and the bars, plates, or other form of castings are ready at once to further manipulations of rolling, drawing, forging, the

The new quarternary alloy herein described, composed of copper, aluminium, tungsten and phosphorus, and having the characteristics referred to, is known as cyrnium.

W hat we claim is-- 1. The new quarternary alloy, composed of copper, aluminium, tungsten and phosphorus in substantially the proportions set forth.

2. The process herein described for prod ucing the quarternary alloy herein described, which process consists in first combining copper and tungsten by reducing tungstiferous ore by means of copper in the presence of carbon at a high temperature, adding the desired quantity of copper to the cupro-tungsten mass obtained and melting the resultant compound, adding aluminium when the mass is perfectly melted, and finally adding phosphorus as set forth.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
