Clad material and method of manufacturing the material

Year	Description
2000	Invention patented by Masaaki Ishio and Yoshiki Takai on February 1st, 2000. Abstract: The present invention, which is aimed at providing a method for manufacturing a clad material that can be used for the anode cases and cathode cases of button-type microbatteries and other miniature electronic devices requiring the use of comparatively thin, drawable sheets, allows the difference between r values, or Lankford values (which characterize the plastic anisotropy between the rolling/bonding direction of a clad material and a direction at a prescribed angle to the rolling/bonding direction) to be reduced by preforming cold rolling at a reduction of 30% or lower in addition to performing a conventional method for manufacturing a clad material, making it possible to substantially enhance the mechanical strength of the clad material and to mass-produce clad materials that have low reduction anisotropy.
