摘要：
A color picture tube shadow mask material is made of an alloy consisting of 30 to 45 wt. % of Ni, 0.1 to 5.0 wt. % of V, and the balance essentially Fe. A color picture tube having a shadow mask consisting of this material is also prepared. The alloy has an average thermal expansion coefficient of 6.times.10.sup.-6 /.degree.C. or less in a temperature range of 20 to 100.degree. C., and an elasticity coefficient of 15,000 kgf/mm.sup.2 or more.
