Abstract
A metal system which comprises a titanium base metal strip, at least one surface having platinum stripes thereon. As a multilayer laminate, there is provided a titanium base metal strip sandwiched between first and second copper layers. At least one surface of the first copper layer facing the titanium has platinum stripes. A method of producing the metal system and laminate, includes the step of initially cleaning bonding surfaces of a first copper strip. During a first processing phase, platinum stripes are cold roll bonded to at least one of the first copper strip surfaces. Excess material is skived from the striped copper strip, then the strip is cleaned. Upon a second process phase, bonding surfaces of the striped first copper layer, a second copper strip layer and a titanium base metal strip are cleaned. Next, the striped first copper layer is placed on the titanium base metal strip, the platinum stripes facing the titanium, and the titanium base metal strip is placed upon the second copper layer. The layers are then cold roll bonded to one another so as to form a multilayer metal system. The resulting system is cold rolled to a selected thickness, then flattened and straightened by roll leveling. The copper may be etched away leaving platinum striped titanium strip.
