Claims19
A housing for an electronic device, comprising:
- an exterior titanium portion;
- an interior metal joined to the exterior titanium portion, the interior metal being a different metal than the exterior titanium portion;
- and
- an intermetallic compound layer having a thickness of less than 1 μm disposed between the interior metal and the exterior titanium portion;
- wherein the intermetallic compound layer is free of discrete oxide particles.

A housing for an electronic device, comprising:
- an exterior titanium portion at least partially defining a first engagement feature;
- and
- an interior aluminum portion joined to the exterior titanium portion, the interior aluminum portion at least partially defining the first engagement feature, wherein:
- a first surface of the exterior titanium portion defining the first engagement feature comprises a first plurality of pores, the first plurality of pores having a first pore density and a first average pore depth;
- and
- a second surface of the interior aluminum portion defining the first engagement feature comprises a second plurality of pores, the second plurality of pores having a second pore density and a second average pore depth.
