Aluminum alloy with additions of magnesium, calcium and at least one of chromium, manganese and zirconium, and method of manufacturing the same

Provided are an alloy production method that may easily distribute a compound in a matrix of an alloy while maintaining the quality of a molten metal, and an alloy produced by the same. In accordance with an exemplary embodiment, the method includes forming a molten metal in which a mother alloy including at least one kind of first compound and a casting metal are melted, and casting the molten metal, wherein the mother alloy is a magnesium mother alloy or aluminum mother alloy.

Alloy production method and alloy produced by the same

Provided are an aluminum alloy improving mechanical characteristics by allowing a magnesium-silicon compound to be distributed in an aluminum matrix without performing a heat treatment, and a production method thereof. In accordance with an aspect of the present disclosure, there is provided a method of producing an aluminum alloy, including: melting a magnesium mother alloy including a magnesium-silicon compound, and aluminum to form a molten metal; and casting the molten metal.

Aluminum alloy and production method thereof

Provided are an aluminum alloy and a production method thereof. In accordance with an embodiment, an aluminum-based mother material is melted to form a molten metal. An additive including silicon oxide is added to the molten metal. At least a portion of the silicon oxide is exhausted in the molten metal. The molten metal is cast.

Provided are an aluminum alloy and a manufacturing method thereof. In the method, aluminum and a master alloy containing a calcium (Ca)-based compound are provided. A melt is prepared, in which the master alloy and the Al are melted. The aluminum alloy may be manufactured by casting the melt.
