Description
Patented Apr. 25, 1933 UNITED STATES PATENT OFFICE ERNST DE REDER AND HUBERT ALTWICKEB, OF BITTERFELD, GERMANY, ASSIGNORS,
BY MESNE ASSIGNMENTS, T MAGNESIUM DEVELOPMENT CORPORATION, A COB- roRA'rIon or nnnawm annoy No Drawing. Original application filed September 20, 1929, Serial No. 394,119. Divided and this application filed June 23,
This invention relates to the manufacture of shaped articles from sheets of magnesium Drawing hollow articles, of which this' application is a divisional application, we have described and claimed a method of drawing hollow articles from sheets of magnesium and magnesium alloys which comprises drawing the sheets within a temperature ran e, in which the transverse properties exceed t e longitudinal properties of the sheet, i. e. at
to at least about temperatures amounting 270 (1., and preferably about 350 C.
We have further found that the application of such temperatures not only renders possible the drawing of hollow articles from sheets of technically pure imagnesium, but that the-latter metal may also be hardened by the addition of limited amounts of zinc and aluminium without forfeiting its favourable properties in the process in question.
Magnesium alloys particularly suitable for this purpose contain between about 0.5 and about 3'percent of zinc, and between about 0.5 and 6.5 percent of aluminium, besides between about 0.2 and 1.5 percent of manganese, the presence of the latter metal tending to diminish the liability of the alloys to corrode without noticeably influencing their plasticity. A preferred alloy consists of about 1 percent of zinc, about 6.5 percent of alu 1931. Serial No. 546,362.
1.5 percent, zinc from about 0.5 to about 3 percent, aluminium from about 0.5 to about 6.5 percent, balance magnesium.
2'. An alloy in sheet form having the characteristic of being drawn or embossed, consisting of about 1 percent of zinc, about 6.5 percent of aluminium, about 0.3 percent of manganese, balance ma esium.
In testimony whereo we have hereunto set our hands.

the balance being magnesium.
We claim 1. An alloy in sheet form having the characteristic of being drawn or embossed consisting of, manganese between about0.2 and
