Definitions
- the object of this invention is a new aluminium alloy and the process employed in its manufacture.
- the new metal is a white silvery compound, of which the density does not exceed 2,7. Very elastic malleable and ductile, and more tenacious than copper, this metal beats out, embosses, hammers, bends, wiredraws, and welds very easily. It can be worked without the use of special tools.
- This alloy furthermore possesses reat tensile strength and is not substantial y oxidizable in air or water. It is particularly useful in cases where 1t is exposed to the action of seawater, which 1t has been found to success- I fully resist. In addition the new metal is not seriously attacked by any acid with the exception of hydrochloric acid.
- the following process is employed; about 20% of the aluminium to be employed is first melted down in a suitable bath and when the temperature has reached about 750 C. the copper is added 3 when the fusion of this last metal is complete the zinc is added and afterward the iron. After the complete fusion of this mixture the remaining 80% of the aluminium is added.
- the fluid mass is then withdrawn from the fire and the magnesium is incorporated with it.
- aluminium alloy having the following proportions. Aluminium about 99,020%, iron 0,310%, zinc 0,010%, magnesium 0,041%, copper 0,610%, substantially as described.

UNITED STATES PATENT OFFICE.
ALUMINIUM ALLOY.
No. 856,392. Specification of Letters Patent. Patented June 1 1, 1907.
Application filed January 12, 1.907. Serial No. 351,985.
To a'ZZ whom it may concern:
Be it known that I, ALEXANDRE CHAM- BAUD, residing in Paris, France, 9 Rue St. Georges, have invented certain new and useful Improvements Relating to Aluminium Alloys.
The object of this invention is a new aluminium alloy and the process employed in its manufacture.
Numerous alloys of aluminium are already known but the alloy which is the subject of this invention is distinguished from those hitherto obtained by the nature and propor- These proportions are of considerable importance in that they give to the alloy particular and eminently characteristic qualities which are indicated below. The proportions of its constituent elements are as follows :--Aluminium 9'9,020%, iron 0,310%, zinc 0.010%, magnesium 0,041%, copper 0,610%. The remaining 0,009% is comprised of the silica which is found in the aluminium.
The above proportions have appeared to give the best practical result, but the right is reserved to modify these proportions within certain measures without exceeding the limits of the invention. a
The new metal is a white silvery compound, of which the density does not exceed 2,7. Very elastic malleable and ductile, and more tenacious than copper, this metal beats out, embosses, hammers, bends, wiredraws, and welds very easily. It can be worked without the use of special tools. This alloy furthermore possesses reat tensile strength and is not substantial y oxidizable in air or water. It is particularly useful in cases where 1t is exposed to the action of seawater, which 1t has been found to success- I fully resist. In addition the new metal is not seriously attacked by any acid with the exception of hydrochloric acid.
To obtain the metal, the following process is employed; about 20% of the aluminium to be employed is first melted down in a suitable bath and when the temperature has reached about 750 C. the copper is added 3 when the fusion of this last metal is complete the zinc is added and afterward the iron. After the complete fusion of this mixture the remaining 80% of the aluminium is added.
The fluid mass is then withdrawn from the fire and the magnesium is incorporated with it.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
l 1. An aluminium alloy having the following proportions. Aluminium about 99,020%, iron 0,310%, zinc 0,010%, magnesium 0,041%, copper 0,610%, substantially as described.
2. The process of manufacture of aluminium alloy consisting in first melting about 20% of the aluminium to be employed and when the temperature has reached about 750 C. in addin copper and when the fusion of this last metal is complete in adding zinc and afterward iron and after the complete fusion of this mixture, in adding the remaining 80% of the aluminium and finally in incorporating magnesium when the fluid mass is withdrawn from the fire as substantially described.
ALEXANDRE CHAMBAUD.
