Alloys for Casting. F. DE BUIGN~, Magdeburg. (Eng. Pat.

1346, of I912.)--Type-metal alloys designed for casting under pressure should be capable of remaining in the molten condition for a long time without changing in composition, and should not form dirt or dross in the casting channels or moulds. Alloys composed of aluminum, copper, and tungsten, and free from zinc, fulfill these conditions. Alloys which give satisfactory results are (I) aluminum 80 to 9 o, copper 8 to IO, tungsten I to IO parts, and (2) copper 9 ° to 95, aluminum 3 to IO, tungsten o.I to 5.0 parts. Both alloys must be free from zinc.
