Abstract (en)

[origin: EP0756015A1] Alloy is used to make a mask for use inside a cathode ray tube and comprises 69-83 wt.% Ni, and up to the following amounts of other elements with the residue being Fe: 7% Mo, 8% Cu, 1.5% Co, 7% W, 7% Nb, 7% V, 7% Cr, 7% Ta, 0.1% C, 1% Mn, 1% Si, 1.2% Ti, 1.2% Al, 1.2% Zr, 1.2% Hf and 0.010% S. The following equations also restrict the percentages: Co+Ni+1.5 x Cu ≥ 79.5%; 3 x (Co+Ni)-2 x Cu ≥ 206%; Co+Ni+7 x Cu ≤ 130%; 7 x(Co+Ni)+2 x Cu ≤ 581%; Mo+W+Nb+V+Cr+Ta ≤ 7%; Ti+Al+Zr+Hf ≤ 1.2%; C+Mn+Si ≤ 1%; 80.5 ≤ Co+Ni+0.80 x Cu ≤ 81.7%. The mask is also claimed.
