Definitions
- the invention relates to a low-expansion iron-nickel alloy.
- iron-based alloys with 36% nickel have a low coefficient of expansion in the temperature range of 20 and 100 ° C. For this reason, these alloys have been used for several decades where constant lengths are required even when the temperature changes, such as precision instruments, watches, bimetals. With the development of color television sets and computer monitors in the direction of higher resolution, color fidelity and contrast strength even under unfavorable lighting conditions, and especially with regard to the development of ever flatter and larger screens, iron-nickel materials are increasingly being used for shadow masks.
- an iron-based alloy with at least 34% nickel with a lower coefficient of thermal expansion in the temperature range from 20 to 100 ° C of below 1.0 x 10 -6 / K could be developed according to DE-A 4402684 by the Manganese content was kept lower than 0.1% and the iron-nickel ratio Fe / Ni was chosen between 1.75 and 1.83.
- Typical values of the coefficient of thermal expansion in the temperature range from 20 to 100 ° C are between 0.6 and 0.9 x 10 -6 / K.
- the DE-A 22 17 280 relates to a pinhole in color picture tubes, the material of which an iron-nickel alloy having a temperature range of 20 - 80 ° specific thermal expansion of 0-2, preferably of 0.6 to 1.2 x 10 - 6 / C of the following composition (in% by weight) is: 30 - 45% Ni, 0 - 2.5% Mn, 0 - 2% Si, 0 - 2% C, 0 - 8% Co, 0 - 11% Cr, 0 - 3% W, balance iron.
- a preferred alloy should have the following composition (in% by weight): 30-31% Ni, 4-8, preferably 5-7% Co, balance iron.
- An iron-nickel alloy is known from JP-A 6-336655, which with Ni content between 35 and 36% by weight Co content between 0 and 0.7% by weight having.
- an alloy is required that achieves a thermal expansion coefficient in the temperature range from 20 to 100 ° C even below 1.0 x 10 -6 / K.
- the alloy costs must be significantly lower than that of the iron-based alloy with about 32% nickel and 5% cobalt.
- JP-A 06336655 contains an iron-nickel (cobalt) alloy for shadow masks described, which can have the following composition: ⁇ 0.35% Mn, ⁇ 0.020% Al, ⁇ 0.09% Si, ⁇ 0.06% Cr, ⁇ 0.03% Ti, ⁇ 0.06% Mo, ⁇ 0.04% W, ⁇ 0.03% Nb, ⁇ 0.02% V, ⁇ 0.03% Cu and ⁇ 0.10% Ti + Cr + Al + Cu.
- the nickel content should between 28% and 38%, the rest Fe. Depending on the nickel content can be added between 1 and 7% cobalt. As already mentioned cobalt is an expensive alloying element that can be largely replaced.
- EP-A 0567989 is a shadow mask material, a method of manufacturing the same and a color picture tube with such a material.
- An Fe-Ni alloy with (in mass%) 30 - 40% Ni, rest Fe, is used. Up to 10% of the nickel can be replaced by cobalt.
- On permissible Impurities are considered in the following contents: C ⁇ 0.005%, S ⁇ 0.005%, P ⁇ 0.005%, O ⁇ 0.005%, N ⁇ 0.005%.
- Nb Nb, Ti, Zr, Mo, V, W, Be, Si, Al, Ta.
- the purpose of this publication is the textures of the Optimize shadow mask material.
- US-A-5811918 describes a shadow mask material with ⁇ 20 ° - 100 ° C ⁇ 0.9 x 10 -6 / ° C, the alloy contains 35 - 37% NI, less than 0.1 of (each) Mn, Cr and Si, and Max 0.9% Co.
- the object of the invention is a low-expansion iron-nickel alloy provide the use of inexpensive alloy elements nevertheless optimal thermal expansion coefficients in the temperature range reached from 20 - 100 ° C and can be used for different applications should be.
- the alloy must, especially when processing the alloy Shadow masks for color television sets, good hot and cold formability exhibit.
- Cobalt contents lower than 0.5% do not achieve the desired effect.
- the alloy according to the invention draws excels in processability and demands from Production of shadow masks no additional process steps. she shows furthermore a long-term stability of their thermal properties.
- the alloy according to the invention achieves very low coefficients of thermal expansion in the temperature range from 20 to 100 ° C. from below 0.6 x 10 -6 / K.
- a higher manganese content is at least 0.2% essential for good hot formability.
- the alloy according to the invention is also very low manganese contents of less than 0.05% both warm and very good is cold formable.
