Field of the Invention The present invention relates to a metal case, and more particularly to a metal case having a plurality of materials. [Prior Art] With the development of electronic technology, a variety of electronic devices such as mobile phones and computers have emerged, enabling consumers to fully enjoy the convenience brought by electronic technology anytime and anywhere. As one of the main components of electronic devices, the shell has become more and more concerned and valued by its texture and aesthetics. The electronic device housing generally uses plastic as its main material, but this kind of housing has great disadvantages in terms of strength and resistance to electromagnetic radiation. With the development of metal forming technology, in recent years, portable electronic device casings made of metal or alloys thereof have appeared, such as stainless steel, alloys, titanium alloys, and the like. The several metal materials each have different appearance texture and enthalpy properties. ^ Know the metal shell ϋ more (four) single - the non-recorded steel, Ming materials or Qin Jin and other materials made 'in order to achieve the desired effect, or use a different gold material components through the group to form a variety of metal texture = . However, the method cannot form a body having a plurality of metallic outer feelings. SUMMARY OF THE INVENTION A metal housing that is integrally formed and does not require a surface feel. In view of the above, it is necessary to provide __ treatment to have a variety of metal appearance quality 200936370 A metal casing, comprising a metal bottom layer and a metal surface layer, the metal surface layer is a metal composite layer, which is formed by a plurality of metal layers connected, And the material of each adjacent two metal layers is different, and the metal surface layer is formed on at least one surface of the metal underlayer. The metal surface layer of the metal body of the present invention comprises a metal layer which is made of different metal materials, so that the metal shell can have a variety of metal appearance textures without surface treatment. < ❿ [Embodiment] Referring to Figures 1 and 2, a preferred embodiment of the present invention is a metal casing ° metal base layer 110 and a metal skin layer 120. The metal surface layer 120 is a full-fledged manganese layer, and the metallization layer (2) and the plurality of second-level f-f include a plurality of first 121 and second metal layers 』2; the first metal layer 110 ^ ^ is replaced by a parent Side by side connected to the metal underlayer (2), the first metal: the metal surface layer 120 is formed. The shape of the first metal layer Ο H 2 may be a linear stripe or a wavy stripe c material, but the material of the gold eyebrow layer 121 and the second metal layer 122 may be made of a second metal layer 1221 layer 11 〇 The first metal layer 121,

For example, the metal underlayer 11C layer 122 can be one of two, respectively, the shell '! the first metal I 121, the second metal is excited, and the steel is not. When it belongs to the casing 10, the first metal layer 121, the first layer 121, and the lower layer of the bottom layer 110 may be supplied to the first metal layer 121, the first layer 121, and the first metal layer 122. The f-materials of the strip 9 of the bottom layer are alternately laid on the surface of the metal, and then the strips of the first metal layer 121, the second metal layer 22 and the metal underlayer 110 are combined by a pressure action method such as rolling 200936370. The composite material is combined to obtain a composite material, and finally the k-metal ruthenium 10 is obtained from the lap material by a conventional conventional metal forming method such as press forming. The formation of the composite material may also be obtained by exploding a strip of the first metal layer 122 and the metal underlayer. The thickness of the fabricated metal casing 1 can be determined by the ratio of the thickness of the metal base m to the thickness of the metal skin 12. It is understood that the metal skin 120 may also be formed on the other opposite surface of the metal underlayer 110 at the same time. For example, the casing 10 can be used for an outer casing of an electronic product, a casing such as a casing, a cover body, and a computer compartment, and the metal casing 1 can also be a container, such as a glasses case and a stationery sensitive metal member 2; the metal casing 1 〇 can also be glasses frames, fine dragons gift boxes and boxes. Forming, the metal surface layer 120 can be a plurality of metal layers side by side together with the material of each adjacent two metal layers of the surface layer 12〇. The metal surface layer 120 of the metal shell 10 of the present invention is white = the metal layer is formed, thereby making the metal The casing metal material has a variety of metallic appearance textures at the same time. .,,,- Surface treatment can be [Simplified illustration] Figure. 1 is a perspective view of a metal casing according to a preferred embodiment of the present invention. 8 200936370 FIG. 2 is a schematic cross-sectional view showing a metal casing according to a preferred embodiment of the present invention.
