PROVISIONAL SPECIFICATION.
An Improved Metallic Alloy.
I DAVID WILLIAM SUGG of Vincent Street in the City of Westminster,
Engineer, do hereby declare the nature of this invention to be as follows:-
:-
This invention consists in the production of a metallic alloy from copper, zinc,
and aluminium.
In carrying out my invention, I take 50 parts of copper, 40 parts of zinc, and the
aluminium in the proportion of 2 (two and a half) per cent. of the whole. These
proportions will give the lowest class of the alloy that will be of any use for
manufacturing purposes, but a richer alloy may be obtained by using other
proportions of the copper and zinc, the proportion of aluminium remaining the
same, namely, 2 per cent. of the whole.
The mode of preparing the alloy will vary somewhat, according to the nature of
the alloy required; thus, if a hard metal is desired, the copper and the aluminium
are first mixed together to form a copper alloy, and while in a molten state, the
zinc is added in small pieces during continuous agitation. The resulting alloy,
which will be of a red color, somewhat like pure gold, will take a high polish.
If, on the contrary a ductile metal is required, the zinc and aluminium are first
mixed, to form a zinc alloy, and the copper is then added.
The resulting alloy, in this case, will have the appearance of brass, but in both
cases a non-oxidisable metal is obtained, and one that is proof against the action of
sea water, and, to a large extent, against the action of acids.

I DAVID WILLIAM SUGG of Vincent Street in the City of Westminster,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The improved metallic alloy, consisting of a mixture of copper, zinc, and
aluminium, in or about the proportions given.
2. The production of a metallic alloy from copper, zinc, and aluminium,
substantially as herein described.
