摘要： Disclosed are a manganese-aluminum alloy and its preparation method. The manganese-aluminum alloy comprises, by weight, 5% to 90% of manganese and the balance of aluminum. The method comprises: adding metal aluminum or molten aluminum to a container, the temperature of the molten aluminum being between 700° C. and 800° C.; adding a metal manganese raw material to the molten aluminum, closing a furnace cover, measuring the pressure, and introducing argon to ensure that the interior of a magnetic induction furnace is in a positive-pressure state, and stirring the mixture with a graphite stirring head; powering on and heating the metal aluminum or the molten aluminum to 1000° C. or above, melting, and holding the temperature between 1000° C. and 1500° C.; and after alloying is completed, cooling to 850° C. or below, opening the furnace cover, and taking a manganese-aluminum alloy out.

摘要： Disclosed are an iron-aluminum alloy and its preparation method. The iron-aluminum alloy comprises, by weight, 50% to 80% of iron and the balance of aluminum. The method comprises: adding metal aluminum or molten aluminum to a container, wherein the temperature of the molten aluminum is between 700° C. and 800° C.; adding a metal iron raw material to the molten aluminum, closing a furnace cover, measuring the pressure, and introducing argon to ensure that the interior of a magnetic induction furnace is in a positive-pressure state, and stirring the mixture with a graphite stirring head; powering on and heating so that the metal aluminum or the molten aluminum is heated to 1000° C. or above and molten, and holding the temperature between 1000° C. and 1500° C.; and after alloying is completed, cooling to about 1000 t, opening the furnace cover, and taking the iron-aluminum alloy out.

摘要： Disclosed are a silicon-aluminum alloy and its preparation method. The method comprises: adding aluminum metal or molten aluminum into a container, wherein the temperature of the molten aluminum is between 700° C. and 800° C.; adding a semi-metallic silicon raw material to the molten aluminum, closing a furnace cover, carrying out vacuumization, and introducing argon, to ensure that the interior of a magnetic induction furnace is in a positive-pressure state, and stirring the aluminum metal or molten aluminum with a graphite stirring head; powering on and heating so that the aluminum metal or molten aluminum is heated to 1000° C. or above and molten, and holding the temperature between 1000° C. and 1500° C.; and after alloying is completed, cooling the molten aluminum to 1000° C. or below, opening the furnace cover, pouring the silicon-aluminum alloy into a corresponding mold, and cooling for molding.
