Magnetostriction control alloy sheet, a part of a braun tube, and a manufacturing method for a magnetostriction control alloy sheet |
摘要 |
The invention relates to a magnetostriction control alloy sheet advantageously used as a high resolution shadow mask having a low coefficient of thermal expansion, superior magnetic properties and a high Young's modulus after a blackening process, a manufacturing process for the same, and a part for a color Braun tube such as a shadow mask. The magnetostriction control alloy sheet comprises C at 0.01 wt. % or less, Ni at 30 to 36 wt. %, Co at 1 to 5.0 wt. %, and Cr at 0.1 to 2 wt. %, the remainder Fe and unavoidable impurities, and having a magnetostrictionlambd after the softening and annealing of (-15x10-6) to (25x10-6).
