Housing for a camera and method of manufacture

A method of forming an assembly of a first element formed of a first material and a second element formed of a second material, in which the first element includes a target region, the method comprising

• providing the first element, the first element having an original material structure corresponding to an original set of material properties, the original material structure extending uniformly throughout at least a volume defined by the target region of the first element,
• heat treating the target region of the first element such that at least a portion of the outer surface of the target region has a modified material structure corresponding to a modified set of material properties and other portions of the target region retain the material properties corresponding to the original set of material properties, the modified set of material properties being different from the original material properties,
• providing the second element,
• positioning the first element and the second element so that the portion of the outer surface of the target region of the first element physically contacts the second element while in a predetermined configuration,
• forming a bond between the portion of the outer surface of the target region of the first element and the second element, whereby the second element is connected to the first element in the target region and in the predetermined configuration.
