Further, when the oxygen-free continuous casting and rolling are carried out, the steel wire is fed into the semi-molten aluminum layer, the feeding angle of the steel wire is controlled, and the position of the steel wire in the semi-molten aluminum alloy can be controlled, so that the final steel wire position types can be two, one is that the steel wire is completely wrapped by the semi-molten aluminum alloy, and the other is that the steel wire is tangent to the copper layer close to the surface of the aluminum layer.
In the high-frequency circuit, the current is mainly distributed on the surface of the conductor due to the obvious skin effect, the aluminum-copper-silver composite metal material fully utilizes the skin effect, and in the high-frequency circuit, the current is mainly distributed on the silver layer, and the current distribution in the aluminum layer and the copper layer is less, so that the aluminum-copper-silver composite metal material is superior to the silver material, the copper material and the aluminum material which are only used under the same thickness.
