Definitions
- This invention has for its object the inexpensive production of an alloy which is readily capable of die casting without force or pressure which heretofore has been necessary with hard metals and which possesses such desirable qualities as to strength, hardness and capability of accurate machining as to permit its satisfactory and economical substitution for brass castings and for all purposes where a non-rusting high quality metal is desirable.
- a further object is the production of an alloy of this character which is substantially free from crystallization even when subjected to prolonged and violent vibration and which is capable of being melted at a comparatively low temperature and consequently a practical and economical material for use in die casting.
- the alloy consists of two metals only, namely, commercial Zinc and aluminum preferably combined in the proportion of 84- per cent zinc and 16 per cent aluminum, although these proportions are susceptible of limited variations, for instance, the pro portion of zinc may vary from 80 to 87 per cent and the aluminum accordingly, but the high quality of the alloy is impaired when the stated range in proportions of the two metals is further varied, wider deviations from these specific proportions producing radically different results.
- the aluminum having a higher melting poin than zinc, is melted first and brought to a red heat visible in daylight and the zinc is subsequently added, the mixture being maintained at a red heat for one hour after which it may be immediately used for molding and die casting.
- This alloy produced with the prescribed proportions of zinc and aluminum possesses great strength and hardness and excellent machining qualities, being suitable for bear ings and in fact for all work where brass castings are used.
- the alloy possesses an extremely low factor of shrinkage ordinarily approximating five sixtyfourths of an inch of the lineal foot What is claimed is:
- An alloy consisting of from 80 to 87 per cent zinc and from 20 to 13 per cent aluminum.

UNITED STATES PATENT OFFICE.
ALLOY.
Specification of Letters Patent.
Patented May 23, 1922.
Application filed November 29, 1920. Serial No. 427,003.
To all whom it may concern:
Be it known that I, ALoNzo U. RANDALL, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in an Alloy, of which the following is a specification.
This invention has for its object the inexpensive production of an alloy which is readily capable of die casting without force or pressure which heretofore has been necessary with hard metals and which possesses such desirable qualities as to strength, hardness and capability of accurate machining as to permit its satisfactory and economical substitution for brass castings and for all purposes where a non-rusting high quality metal is desirable.
A further object is the production of an alloy of this character which is substantially free from crystallization even when subjected to prolonged and violent vibration and which is capable of being melted at a comparatively low temperature and consequently a practical and economical material for use in die casting.
The alloy consists of two metals only, namely, commercial Zinc and aluminum preferably combined in the proportion of 84- per cent zinc and 16 per cent aluminum, although these proportions are susceptible of limited variations, for instance, the pro portion of zinc may vary from 80 to 87 per cent and the aluminum accordingly, but the high quality of the alloy is impaired when the stated range in proportions of the two metals is further varied, wider deviations from these specific proportions producing radically different results.
In the production of the alloy, the aluminum, having a higher melting poin than zinc, is melted first and brought to a red heat visible in daylight and the zinc is subsequently added, the mixture being maintained at a red heat for one hour after which it may be immediately used for molding and die casting.
This alloy produced with the prescribed proportions of zinc and aluminum possesses great strength and hardness and excellent machining qualities, being suitable for bear ings and in fact for all work where brass castings are used. In addition, the alloy possesses an extremely low factor of shrinkage ordinarily approximating five sixtyfourths of an inch of the lineal foot What is claimed is:
1. An alloy consisting of from 80 to 87 per cent zinc and from 20 to 13 per cent aluminum.
2. An alloy consisting of 84: per cent zinc and 16 per cent aluminum.
In testimony whereof, I aiiix my signature hereto.
ALONZO U. RANDALL.
