There is disclosed a process for producing strip material useful for making lead frames which includes preparing a ferritic stainless steel substrate as a thin strip and, before subjecting it to finish rolling, electroplating it with a first layer of copper and an outside layer of nickel or tin, after which the strip is precision rolled to final gauge. There is also disclosed the product from this process which is a precision rolled strip having a core of ferritic stainless steel and a continuous surface layer of nickel or tin with an intermediate layer of copper.

An amorphous Fe-B-Si alloy and article made therefrom is provided having improved castability while maintaining good magnetic properties, ductility and improved thermal stability. Fe-B-Si alloys containing 0. 1-4. 0% Cr, in atomic percent, have improved castability and amorphousness. An alloy is provided generally consisting essentially of 6-10% B, 14-17% Si, 0. 1-4. 0% Cr, and the balance iron, and no more than incidental impurities. A method of casting an amorphous strip material from the alloy is also provided.

An aperture mask comprised of a nickel-iron alloy having a low thermal expansion for a color CRT is produced by combining a first annealing to produce a low coercive force and mechanical properties desirable for a warm forming operation during which a desired profile of the mask is produced with minimized springback and a second annealing after forming to provide a stress free low coercive force mask also having an oxidized high thermal emissivity surface. Wherein the process requires control of the atmospheres and oxidizing potentials in the two annealing steps.
