COMPOSITE VACUUM DEPOSITION MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: To solve the problem that the production of a several-hundred meter or longer product and the control of a metal content are difficult in producing a composite vacuum deposition material composed of an aluminum core and a metal applied thereto by cold-drawing a metal rod inserted into an aluminum pipe. CONSTITUTION: The long composite vacuum deposition material in which the weight of its core part is 8-33 wt.% of the entire weight, the composition is stabilized, and an aluminum metallic material and a metal of the core part are firmly joined together can be provided inexpensively in good yields by producing a first base material prepared by coating the metal with the aluminum metallic material by conformity extrusion and obtaining a second base material by cold-drawing the first base material.
