Methods and apparatus for forming a multi-layered metal structure that includes an anodized surface are disclosed. According to one aspect, a housing arrangement can include a stainless steel layer and at least a first layer. The first layer can have a first bonding surface and a first exterior surface. The first bonding surface can be substantially bonded in direct contact with the stainless steel layer, and the first exterior surface can be an exterior of the housing arrangement. The first exterior surface is an anodized surface. In one embodiment, the first layer can be formed from an anodizable material such as aluminum, titanium, niobium, or tantalum.

1. A method of anodizing selected portions of a housing of an electronic device, the housing including a multi-layered metal sandwich structure having an anodizable exterior laminate layer bound to a first surface of a non-anodizable layer and an anodizable interior laminate layer bound to a second
1. A method of anodizing selected portions of a housing of an electronic device, the housing including a multi-layered metal sandwich structure having an anodizable exterior laminate layer bound to a first surface of a non-anodizable layer and an anodizable interior laminate layer bound to a second surface of the non-anodizable layer, the method comprising: masking a third surface of the non-anodizable layer and a portion of the anodizable exterior laminate layer and interior laminate layer using a mask configured to prevent exposure of the third surface from a subsequent anodizing process;anodizing un-masked portions of the anodizable exterior laminate layer and interior laminate layer by exposing the multi-layered metal sandwich structure to an anodizing process; andremoving the mask by cutting away the mask and the third surface of the non-anodizable layer and a portion of the anodizable exterior laminate layer and interior laminate layer. 2. The method of claim 1, wherein the non-anodizable layer is comprised of a stainless steel. 3. The method of claim 1, wherein the non-anodizable layer is more rigid than the anodizable exterior and interior laminate layers. 4. The method of claim 1, wherein the anodizable exterior laminate layer and the anodizable interior laminate layer are each comprised of one or more of aluminum, titanium, niobium and tantalum. 5. The method of claim 1, wherein the anodizable exterior laminate layer has a greater thickness than the anodizable interior laminate layer. 6. The method of claim 1, further comprising: etching a portion of anodized exterior and interior laminate layers exposing a corresponding portion of the non-anodizable layer. 7. A method of anodizing a selected portion of a housing for an electronic device, the housing including a non-anodizable structure comprised of a non-anodizable material, the method comprising: binding an anodizable layer to a first surface of the non-anodizable structure;masking a second surface of the non-anodizable structure with a mask configured to prevent exposure of the second surface to a subsequent anodizing process, wherein the second surface is not bonded to anodizable layer;anodizing the anodizable layer by exposing the housing to an anodizing process, andremoving the mask by cutting away the mask and the second surface of the non-anodizable structure. 8. The method of claim 7, further comprising: removing the mask from the second surface of the non-anodizable structure. 9. The method of claim 8, wherein the non-anodizable structure is comprised of a metal. 10. The method of claim 9, wherein the metal is comprised of stainless steel. 11. The method of claim 8, wherein the non-anodizable structure is more rigid than the anodizable layer. 12. The method of claim 8, wherein masking the second surface includes masking at least a portion of the anodizable layer. 13. A method of anodizing a housing for an electronic device, the housing including a non-anodizable structure comprised of a non-anodizable material, the method comprising: cladding an anodizable layer to a first surface of the non-anodizable structure;applying a mask on a sacrificial surface of the non-anodizable structure that is not clad to the anodizable layer, wherein the mask is configured to prevent exposure of the sacrificial surface from a subsequent anodizing process;anodizing the anodizable layer by exposing the housing to the anodizing process; andremoving the mask by cutting away the mask and the sacrificial surface of the non-anodizable structure. 14. The method of claim 13, wherein applying a mask on a sacrificial surface includes creating a substantially water-tight seal covering the sacrificial surface. 15. The method of claim 13, wherein applying a mask on a sacrificial surface includes applying the mask over a portion of the anodizable layer. 16. The method of claim 13, wherein the first surface of the non-anodizable structure includes an interior surface of the non-anodizable structure and an exterior surface of the non-anodizable structure. 17. The method of claim 13, further comprising: prior to applying the mask, creating a shape of the housing by draw-forming the clad anodizable layer and non-anodizable structure. 18. The method of claim 13, wherein the non-anodizable structure is more rigid than the anodizable layer. 19. The method of claim 13, wherein the non-anodizable structure is comprised of stainless steel.
