ABSTRACT:
Methods for producing zirconium strips that demonstrate improved formability are disclosed. The zirconium strips of the present disclosure have a purity and crystalline microstructure suitable for improved formability, for example, in the manufacture of certain articles such as panels for plate heat exchangers and high performance tower packing components. Other embodiments disclosed herein relate to formed substantially pure zirconium strip, articles of manufacture produced from the substantially pure zirconium strip, and methods for making the articles of manufacture.
