Description of the Invention: [Technical Field] The present invention relates to a metal body, and relates to a metal casing having a plurality of materials. [Prior Art] With the development of electronic technology, various electronic devices such as mobile phones and computers are in competition (4), so that consumers can fully enjoy the convenience brought by electronic technology at any time and place. The aesthetics and tactile effects are also being paid more and more attention by people. The electronic device housing generally uses plastic as its main material, but these two bodies have great disadvantages in terms of strength and anti-electromagnetic radiation capability. With the development of metal forming technology, electronic device housings made of metals or their alloys (such as stainless steel, alloys, titanium alloys, etc.) have emerged in recent years. The metal shells have their own characteristics but also have their own disadvantages. For example, the alloy shells are relatively inexpensive, but the hardness is not enough; the stainless steel and titanium alloy shells have higher hardness, but the cost is higher. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a metal casing having a high hardness and a low cost. A metal casing includes a first metal layer and a metal layer, and the first metal layer is formed on the second metal layer, the copper layer is made of copper, unrecorded steel, titanium or titanium One of the alloy materials, the second metal layer is made of one of aluminum, aluminum alloy or magnesium alloy material. 200938055 The metal shell of the present invention has a higher hardness due to the first metal layer and the second metal layer, respectively. Made of low-cost metal, the metal casing has the dual advantages of high hardness and low cost. 1 and 2, a metal case 10 according to a preferred embodiment of the present invention includes a first metal layer 11 and a second metal layer 12.

The first metal ^ u may be made of a metal material having a relatively high hardness such as copper, stainless steel, chin or titanium alloy. The twelfth can be made of a low-cost metal such as an alloy, an aluminum alloy, or a magnesium alloy. The metal layer 11 is used as the inner layer of the metal casing 1 and the second metal layer 12 is used as the metal shell. The outer layer of the body 1 is formed by the first metal layer u, and the outer surface thereof is formed by the second metal layer 12. The first metal layer u is a metal shell w ❹ Provides higher mechanical strength, while the second metal, 12 shells,! Diversified surface treatments such as anodizing, chemical film formation and coating can be used to achieve rich appearance characteristics. When the first metal layer 11 is used as an outer layer of the metal case 1 , the second metal layer 12 is used as an inner layer of the metal case 1 , that is, the outer surface of the metal case 1 is formed by the first metal When the inner surface is formed by the metal layer 12, the first metal layer can be made into a thin-walled member which is easy to be stamped and formed, and can realize its unique appearance texture; and because the town and the inscription material are light in weight and relatively inexpensive, It can realize the light weight and high cost performance of the metal shell 200938055 • 1 . When the metal shell is made, the metal layer 12 is combined to obtain the composite material 2 to make the metal layer 11 and the second conventional metal forming method. Then, the composite material passes through - (7). The first metal layer π looks " eight-hard forming to obtain the metal shell-V & /, a metal layer U can be pressure-bonded such as rolling t combination or explosion combination is combined. Ο genus: the thickness of the fabricated metal shell 1〇 can be 〇.3~1_. The thickness of the first layer 第11 and the "" The material properties of the material are determined, for example, if the first metal layer n is an extension or a titanium alloy. The ratio of the thickness of the first metal layer 11 to the thickness of the second metal 乂i not recorded may be 1:4; if the first metal layer 11 is not steel, the ductility is more ductile than the titanium or titanium alloy. It is not easy to process: the ratio of the thickness of the first metal layer U to the second metal layer can be 2: 3. It can be understood that the metal casing 1 can be used for electronic products or home appliances. The electric housing, the cover body, and the computer case, etc.; the metal case 1 can also be a container, such as a glasses case, a pencil case, a cup, a box, etc.; the metal case 1 can also be The eyeglass frame, the exquisite metal gift box, the packaging box, etc. The metal casing 10 of the present invention is made of a metal having a high hardness and a low price due to the first metal layer u and the second metal layer 12, thereby making the metal casing 10 has the advantages of higher hardness and lower cost.
