Abstract

574,615. Alloys. FINSPONGS METALLVERKS AKTIEBOLAG. Feb. 8, 1944, No. 2345. Convention date, Jan. 16, 1943. Drawings to Specification. [Class 82 (i)] [Also in Group XXII] An alloy for extrusion comprises 4 per cent copper, 1.5 magnesium, 0.6 manganese and the rest altiminium, except for the usual amounts of iron and silicon, which alloy will harden by rapid cooling if the extrusion temperature is high enough.
