    Abstract: A tri-metallic material for use in the manufacture of printed circuit boards is described. and the process for its manufacture is described. The tri-metallic material is a sandwich wherein a copper layer is essential the "bread" of the sandwich and an aluminum layer is the filling between both slices of bread. A metallic bonding and/or barrier layer is spread on the aluminum and is selected for its highly non-corrosive properties as well as its bonding, and diffusion inhibiting capabilities.
