RAW MATERIAL FOR MAGNETIC SHIELD, PRODUCTION METHOD THEREOF,AND COLOR TELEVISION RECEIVER

摘要

Magnetic shield materials having excellent inner magnetic shield characteristics and an excellent handling strength, method for producing thereof and color picture tubes produced by incorporating the materials are provided. Th e magnetic shield materials are produced by subjecting hot rolled low carbon steel strips essentially consisting of equal to or less than 0.006 weight % of C, equal to or less than 0.002 weight % of N, equal to or less than 0.5 weight % of Mn, 0.1 - 1.5 weight % of Cu, Fe as a balance and unavoidable impurities to a cold rolling and subsequently annealing the cold rolled steel strips at a temperature of 550 - 850.degree.C.
