- magnesium-antimony alloys herein described may be readily extruded under the same conditions employed in handling the 35 pure metal while at the same time a material is obtained which has appreciably higher strength values than the pure magnesium.
- a magnesium-antimony alloy, for example, containing about 1 per cent of antimony had a tensile strength of about 33,600 pounds per square inch and an elongation of about 3.5 per cent in two inches in the as-extruded condition.
- An increase in the antimony content of 4 per cent served further increase the strength, a value of abo 36,400 pounds per square inch being obtained.
- the elongation inthis case was 5 per cent, somewhat more than in the alloy of lower antimony content.
- the alloy may be prepared in any manner knownto those skilled in the art but preferably I use a rich alloy? for the purpose of adding the antimony because of the vigorous action between molten magnesium and metallic antimony.

mesne assignments, to Magnesium Development Corporation, a corporation of Delaware No Drawing. Application February 6, 1934,
Serial No. 709,970
4 Claims. (ill. 35-1) of the metal, the tensile strength in the as cast con-' dition being about 13,000 pounds per square inch while the rolled metal only has a tensile strength of about 25,000 pounds per square inch. Such 1 limitations in strength have restricted the wider use of the metal.
It is an object of my invention to utilize the inherently advantageous properties of the pure metal and at the same time to overcome some 20 of the handicaps. A particular object is to improve the strength of the metal without substantially diminishing its ductility.
I have found that from about 0.5 to per cent of antimony can be added to magnesium thereby 25 causing a surprisingly large increase in strength;
The weight of the alloy does not differ substantially from that of the unalloyed metal.
For many purposes an extruded product is desirable either by reason of low production cost 30 or because the intricate shape of the article renders difficult other methods of working. I have found that the magnesium-antimony alloys herein described may be readily extruded under the same conditions employed in handling the 35 pure metal while at the same time a material is obtained which has appreciably higher strength values than the pure magnesium. A magnesium-antimony alloy, for example, containing about 1 per cent of antimony had a tensile strength of about 33,600 pounds per square inch and an elongation of about 3.5 per cent in two inches in the as-extruded condition. An increase in the antimony content of 4 per cent served further increase the strength, a value of abo 36,400 pounds per square inch being obtained. The elongation inthis case was 5 per cent, somewhat more than in the alloy of lower antimony content. For most purposes I prefer to use between about 1 and 4 percent of antimony.
The alloy may be prepared in any manner knownto those skilled in the art but preferably I use a rich alloy? for the purpose of adding the antimony because of the vigorous action between molten magnesium and metallic antimony. The use of a rich alloy obviates this dificulty to a great extent.
The term magnesium as used herein and in the appended claims refers to the commercially available metal.
I claim:
. 1. A magnesium base alloy composed of magnesium and from about 0.5 to 5 per cent of antimony.
2. A magnesium base alloy composed of magnesium and from about 1 to 4 per cent of antimony.
3. A magnesium base alloy consisting of magnesium and about 1 per cent antimony.
4. A magnesium base alloy consisting of magnesium and about 4 per cent antimony.
