P COMPOSITION OF HARD LEAD ALLOYS 1 158 675 Specification of Letters Patent.
No Drawing.
To all whom it may concern:
Be it known that we, FRANCIS O. FRARY andS'rERmNe N. TEMPLE, citizens of the United States, and residents, respectively, of Minneapolis, in the county of Hennepin and State of Minnesota, and St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in the Composition of Hard Lead Alloys, of which the following is a specification. r A
Our invention has for its object to provide an improved form of hard lead alloy, adaptable to the customany uses of such alloys.
In order to obtain the necessary hardness and other properties, it has been customary to add a considerable proportion of antimony to the lead. This is at present expensive as compared with lead, and moreover so much of it must be used that the specific gravity of the alloy is very much reduced thereby. For the manufacture of bullets and ammunition it is very desirable to obtain a hard alloy or the maximum specific gravity, in order to concentrate the maximum of kinetic energy in the minimum of volume.
In carrying out ourinvention we use a very small amount of metallic magnesium in a main body of lead. We find that a very small amount of magnesium has as great a hardening eflect as a much greater quantity of antimony, and that less than one per cent. of magnesium is sufficient to produce a hard lead alloy of commercial value. We have also found that the alloy containing a small amount of magnesium is improved by the addition of a small amount of metallic cop per. This causes the alloy to be very tough, and not have the brittleness which characterizes ordinary antimonial lead.
Application filed August 13, 1915. Serial No. 45,379.
We have obtained the best results with alloys containing one-half per cent. of magnesium, or one-half per cent. of magnesium and one-fourth to one-half per cent. of copper. These alloys are very hard, tough, and have a high specific gravity.
-What we claim is:
1. As a new'article of manufacture, hardlead alloys containing in addition'to a main body of lead, a small amount of metallic magnesium.
2. As a new article of manufacture, a
metallic alloy having a main body of lead FRANCIS C. FRY.
