PURPOSE: To provide an inexpensive normal temp. deformable, deep drawable and magnetizable light multilayered composite metal material easy to process and good in heat conductivity. CONSTITUTION: A composite material contains a core layer 1 composed of an aluminum alloy and the core layer l is arranged between two outer layer parts 5, 4, 3 made mutually symmetric with respect to the core layer 1. The outer layer parts contain the pure aluminum layers 5 arranged on the core layer l and carbon steel layers 4 are provided on the layers 5 and, finally, austenite high-grade steel layers forming the outermost layers 3 are laminated. |
