Description
,. SEIKO SHIGETA, OF TOKYO, JAPAN.
MOLYBDENUM BRONZE.
1,319,537. HeDrawing'.
To all whom it may concern:
Be it known that l, Sumo Sincere, a subject of the Empire of Japan, residing at No. 23 Minamifutalmcho, llonjo-Ku, Tokyo, Japan, have invented certain new and useful Improvements in Molybdenum Bronze, of which the following is a specification.
My invention relates to a mol bdenum bronze consistin of an alloy '0 copper, aluminium, 1i10ldenum and tungsten.
The object my invention is the production of a new practical alloy which properties similar to gold as to color, brilliancy, immutability and ductility, etc.
The ingredients of my alloy are copper, aluminium, tungsten and molybdenum, and this alloy is to be produced, for an exam ple, as follows: Copper, molybdenum H'Kl tungsten, each in due proportion, are mixed to ether in a suitable crucible, and after they ave been heated and melted, aluminium is to be added thereto step by step in small quan itics at a time, until the necessary proportion is present, and the whole mixture is meheii aniformly.
In preparing the alloy I prefer to use the said ingredients in the following proportions:
Copper u 80% Aluminium 10% Molybdenum 5 Tlun a slen 5% Among the above ingredients, molybdenum i used to bring the principal cause to nli'ord (lie elizzracieristic as to the man, brilliane' immulability and ductility ol the alley, and tungsten acts mainly to increase Specification 01' Letters Patent.
Patented Get. 21, 1M9.
Application filed June 3, 1918. Serial No. 237,940.
the acid-proof property and tensile strength of the sanie. f tungsten is used in excess, however, this tends to decrease the ductility of the alloy and adds a tinge of red to the same, resulting in an inferior quality of alloy, therefore, it is necessary to suitably adjust the proportion of tungsten according to the use of the alloy to be produced.
My alloy has a color similar to that of eighteen to twenty carat gold, its polished surface possesses a permanent brilliancy which does not become affected by air and moisture, its ductility is high so t let it can be drawn into a fine wire or can be Worked into a thin leaf, it is not eroded by the action of acid or alkali, its tensile strength is great, it has an appropriate hardness so as to suit it for hammering and engraving, and, as a whole, my alloy possesses all the desirable properties of a practical substitute of gold.
I claim :-v
1. A molybdenum bronze consisting of an alloy of a large amount of copper, a much sn'ialler amount of aluminum, and still smaller, but substantial, amounts of molylulenum and tungsten, said alloy having the appearance and many of the other physical properties of gold.
L. An alloy containing about 80% copper, about aluminum and about 5% each of molybdenum and tungsten.
In testimony whereof I slit. my signature in presence of two witnesses.
