Example Embodiment

[0026] The present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0027] Please see figure 1 , Is a schematic flow diagram of a preferred embodiment of a high-hardness electromagnetic shielding aluminum alloy of the present invention. A high-hardness electromagnetic shielding aluminum alloy. The preparation steps of the high-hardness electromagnetic shielding aluminum alloy are as follows:

[0028] Step 1: Add the silicon phase to re-smelt, first prepare Al-xCu-yMg-zZn alloy melt, and then mix the Al-xCu-yMg-zZn alloy melt and Al-12.6Si master alloy uniformly at the melting temperature, After mixing, it is poured into a room temperature metal mold to prepare Mg-11Al-1.0Cu-0.05Zn-mSi aluminum alloy;

[0029] Step two, homogenizing annealing, homogenizing the aluminum alloy ob

Abstract

The invention provides a high-hardness electromagnetic shielding aluminum alloy. The high-hardness electromagnetic shielding aluminum alloy is prepared by using the following steps of adding a siliconphase for re-smelting, carrying out homogenizing annealing, carrying out cleaning and polishing, carrying out soaking, carrying out magnetron sputtering coating, carrying out nickel plating and carrying out cleaning and storing. According to the high-hardness electromagnetic shielding aluminum alloy, solid Al-12.6Si eutectic aluminum silicon is added into the prepared Al-xCu-yMg-zZn alloy melt, and a fine silicon phase is added, so that the hardness is improved; re-smelting and homogenizing annealing are performed, so that the aluminum alloy is uniform in component, and the hardness is improved; then soaking in modified vegetable oil is performed, and then a silicon nitride layer is plated through magnetron sputtering, so that the electromagnetic shielding property of the aluminum alloy is improved; and finally, a nickel layer is electroplated on the aluminum alloy, so that the aluminum alloy is comprehensively protected.
