Fe-Ni-BASED AND Fe-Ni-Co-BASED ALLOY BAR FOR SHADOW MASK

摘要

PROBLEM TO BE SOLVED: To provide a high-strength Fe-Ni-based and Fe-Ni-Co-based alloy bars with high strength for a shadow mask capable of effectively preventing the occurrence of mask unevenness. SOLUTION: In the Fe-Ni-based and Fe-Ni-Co-based alloys which contain Ni of 34-38 mass%, Mn of 0.1-1.0 mass%, C of 0.10 mass% or less and Al of 0.05 mass% or less, the average valueαAVE of the ä100} integration degree distribution in the plate thickness direction on a plate surface is 60% or less and the ä100} integration degreeαcon the plate surface after removing up to 50% of the plate thickness by etching is larger than the ä100} integration degreeαson the plate surface.
