Abstract

The invention discloses an aluminum alloy and a smelting method thereof. Adding sizing agents such as magnesium, silicon and oxidized graphene are attached to the roughening tungsten alloying pellet surface, roughening tungsten alloying pellets are quickly placed into molten aluminum through a tungsten alloying net, and therefore magnesium and silicon ingredients form Mg2Si phases to be added intoan aluminum matrix; and in addition, the oxidized graphene is restored and is evenly scattered in the molten aluminum through a magnesium explosive reaction. According to the aluminum alloy preparedthrough the method, the magnesium and silicon ingredients can be effectively added into the aluminum matrix to form Mg2Si intensified alloying phases, and the conductivity and the mechanical propertyof the aluminum alloy can be greatly improved at the same time through dispersion reduction of the oxidized graphene. In addition, the smelting equipment requirement is low, the process is simple, andthe aluminum alloy and the smelting method are suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of aluminum alloy strengthening and preparation. In particular, it relates to an aluminum alloy and its melting method and application. Background technique [0002] 6××× aluminum alloys have good plasticity, weldability and corrosion resistance, and are widely used in aircraft parts, couplers, electronic devices and joints, etc. The main additive elements of 6××× series aluminum alloys are magnesium and silicon. Whether they can be better added to aluminum alloys directly affects the performance of 6××× series aluminum alloys. Compared with powder metallurgy, the alloys prepared by smelting are denser. , Superior performance, so many alloys currently used in demanding occasions are obtained by smelting methods. However, the traditional smelting process is difficult to add magnesium and silicon elements in the 6××× series aluminum alloys to form Mg 2 Si strengthening phase, when magnesium is added, the aluminum oxi...
