Das this publication, aluminum alloys are travaill4s Identiti G by num6riques d4signationG four digits eg num6roG of Sarie 2xxx, 3xxx, Sxx, 6xxx, etc. The container 52 of molten product reception is arranged below the crucible 54 to receive therefrom a worked aluminum alloy molten charge with a view of a die-casting. As the U. It is the foundation for a full presence in Brazil that will include hydroelectric power, mining, refining and smelting.
It also ushers in a new era of high-rise buildings clad in Alcoa aluminum. For example, the matrices 32 and 34 are, before to inject the molten alloy heated by one or more conventional heating elements electrical resistance not shown placed in channels formed in the dies, or by gas burners or other traditional for matrix-type heating means.
The invention also extends to a pressurized molding process of a worked aluminum alloy member, characterized in that it comprises the steps of die-casting the aluminum alloy worked in a cavity molding at a pressure lower than the ambient pressure in said mold cavity of about 15 to about 50 microns at a rate sd injection supArieore about 75 cenLim Lres per second, eL inLesificaLion a pressure in the range of about 14,500,103 Pa 138 000 x 103 Pa on the aluminum alloy LavaillA s after its injecLion in the molding Cavila.
