Description
Patented Jan. 23, 1940 UNITED STATES PATENT OFFICE MAGNESIUM ALLOY Fritz Christen, Zurich-Altstetten, Switzerland No Drawing. Application April 3, 1939, Serial No. 285,819. In Switzerland December 30, 1937 5 Claims. (01. 75-168) hardness and mechanical strength and capable of being worked by forging, rolling or like operations..
15 The alloy according to the present invention is produced with the aid of the pre-alloy according to application No. 194,221, of which the present application is a continuation in part. This prealloy has the following composition: 2
I 3 and from 4-12% of this pre-alloy is taken and 1 v formed into a final alloy with magnesium forming the remainder. Thealloy thus has a composition falling within the range between:
Percent 35 (1) Aluminum 1.32-1.6.
(2) Zinc 0.94-0.66 (3) Copper 0.70-0.58 (4) Manganese 0.12-0.24 (5) Nickel 0.04-0.12 40 (6) Cobalt -1 l 0.24-0.16
(7 Chromium 0.02-0.036 (8) Molybdenum 0.02-0.004 (9) Magnesium- 96.6 on the one hand and,
Percent (1)- Aluminum 3.96-4.8 (2) Zinc 2.82-1.98 (3) Copper 2.1 -1.74 r (4) Manganese"-.. 0.36-0.72 (5) Nickel 0.12-0.36 (6) Cobalt 0.72-0.48 (7) Chromium. 0.06-0.108 (8) Molybdenum 006-0012 (9) Magnesium 89.8
' on the other hand.
For producing an'alloy within the foregoing range which has favourable properties for forging and exhibits a high tensile strength with small ductility, the composition may be as follows:
Percent (1) Aluminum 1.5 (2) Zinc 1 (3) Copper 1 (4) Manganese 0.5 5 (5) Nickel 0.25 (6) Cobalt 0.24 (7) Chromiumnu 0.05 (8) Molybdenum 0.01 a (9) Magnesium 95.45 10 An alloy which is equally favourable from the point of view of forging but which has a lower tensile strength and a very high ductility can be obtained by selecting the following composition:
- Percent 1) Aluminum 4 (2) Zinc 1.5 (3) Copper L 1.25 (4) Manganese 0.25
(5) Nickel 0.15 (6) Cobalt 0.16 (7.) Chromium 0.02 (8) Molybdenum 0.02 (9) Magnesium 91.65 2
In all cases the alloys are produced in the following way. First of all an alloy as prescribed in application No. 194,221 is produced with the requisite quantities of aluminum, zinc, copper, manganese, nickel, cobalt, chromium, and molybdenum, and the appropriate amount of magnesium as specified in the said application. Pigs of this pre-alloy are placed in the furnace and are covered with a covering salt of known composition which comprises magnesium chloride. When the material has liquefied, pig magnesium is added to the requisite amount and a fresh covering of salt is applied. After a temperature of about 950 C. has been reached heating is discontinued and the liquid metal which is somewhat 4O superheated is thoroughly stirred and is covered again. After the temperature has dropped to about 800 C. the slag is removed and the alloy is cast in moulds of the desired dimensions at about 700 C.
I claim:
