Abstract

The present invention includes casting, e.g., such as by roll casting, or slab casting, an alloy having components in the composition range of about 0.5-1.2% iron, 0.7-1.3% manganese, and 0-0.5% silicon by weight, homogenizing the cast alloy at temperatures below about 1100.degree. F., preferably below about 1050.degree. F. to control the microstructure, and cold rolling to a final product gauge. Such a final product gauge for fin stock applications include thickness in the range of about 0.003-0.006 inch. The cold rolled alloy is then partially annealed to attain desired levels of strength and formability.
