IRON-NICKEL ALLOY STRIP FOR THE MANUFACTURE OF SUPPORT GRIDS FOR INTEGRATED CIRCUITS

摘要

The invention concerns an iron-nickel alloy strip comprising the following expressed in wt. %: 32≰Co+Ni≰45%, 0≰Co≰6.5%, 0≰Cr=6.5%, Cu≰3%, Si≰0.5%, Mn≰0.75%, the rest being made up of iron and unavoidable impurities resulting from production, whereof the microstructure has a recrystallized volume fraction ranging from 3 to 97%, whereof the thickness is less than 0.5 mm. The invention also concerns the use thereof in the manufacture of support grids for integrated circuits.
