Systems and methods for the construction of components such as laminations for the stator core of an ESP motor wherein particles of different materials are mixed and pressed together at an elevated temperature to form a composite material in the desired lamination shape. The materials are selected to provide characteristics such as high magnetic permeability from one material and high thermal conductivity from the other material. The particles of the different materials are pressed together at a temperature that is sufficiently high to fuse the particles together and form a composite material, but is also sufficiently low that the materials are not sintered. The individual materials therefore retain their original characteristics, and the composite material benefits from the high magnetic permeability of the first material and the high thermal conductivity of the other material.
