Description of the Invention (1) The invention is a low expansion iron-nickel alloy. It is known that an iron-based alloy containing 36% nickel has a low coefficient of expansion in a temperature range of 20 to 1000c. As a result, these alloys have been used for decades for applications where a fixed length is required even if the temperature changes, for example, for precision forks, watches, bimetals. The development of color televisions and computer screens with higher resolution, color facsimile, and 7-values (even under adverse light conditions) and especially the development of flatter and larger screens has led to the increased use of iron-nickel alloys as shielding cover. At 20 and 100. (:: The temperature range between them (as it is commonly used in screen tubes), the technology with about 36% nickel f pig iron nickel alloy (in soft annealing energy) has about 1.2 x 10.6 / K or higher thermal expansion coefficient, as indicated by "Stahl-Eisen-Werkstoffblatt, (Steel Materials Paper) (SEW-385, 1991 issue). In order to meet the need for increase, at 20 and 100. . (: The iron-based alloys with a lower thermal expansion coefficient of 1 · 0 X 1〇-6 / K with a minimum thermal expansion coefficient of at least 34% nickel can maintain the manganese content according to DE-A 4402684 Developed below 0.1% and with a Fe / Ni iron-nickel ratio selected between 1.75 and 1.83. Typical values for the coefficient of thermal expansion in the temperature range between 20 and 100 are about 0.6 and 0.9 X 10- Between 6 / Κ. DE-A 22 17 280 is a shielding cover for color image tubes, whose material is 20-80. It has a temperature range of 0-2 (preferably 0.6 to 1.2) x 10 < / C specific thermal expansion iron-nickel alloy, which contains the following composition (by weight%): 30-45% Ni, 0-2.5% Mη, 0-2% Si, 0-2% C, 0 -8% of 〇〇, 〇_11% of (^, 0-3% of ^^, the rest is iron. The preferred alloy should include the following composition (30% to 31% by weight, 4-8 (preferably 5_7)%) This paper size is applicable to China Standard (CNS) A4 specification (21〇χ 297 mm) (Please read the phonetic notation 3 before filling out this page) Order -------- line · 4 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperatives 524Η61 Α7 __ B7 V. Description of the invention (2) Co, the rest is iron. It is known from DE-company's 1973 International Nickel booklet, page 18 and its low temperature 36% nickel iron alloy, which is known as Made from the lower part of the remaining elements (by weight%): C, 0.3% Si, 0.3% Mη, 0.015% S, 0.015% P, 0.05% A, 0.02% Cu, 0.1% Co, 0.1% Cr, and 0.03% Mg. Another company's International Nickel booklet of 1973 reveals iron-nickel alloys on page 12. By replacing 5-6 wt% Ni with Co, it generally contains 36 The thermal expansion coefficient of the iron-nickel alloy by weight% of Qin at room temperature is significantly reduced, but by this, the range of the low expansion coefficient that can be used is limited. By JP-A 6-336655 Iron-nickel alloys with a state content of 35 and 36% by weight are known to contain C0 between 0 and 0.7% by weight. Furthermore, it is known that there are approximately 32% nickel and 5% iron-based alloys starting at 20 and 100%. The temperature range between 0 has a lower coefficient of thermal expansion. Therefore, these alloys are used for the highest requirements regarding hot-length stability. However, due to the high alloy cost of high cobalt content, these alloys have not been widely used for technical applications. As a large-size flat screen shield, the alloy must have a thermal expansion coefficient between 20 and 100 ^: and a thermal expansion coefficient of 丨. 0 χ 10- 6 / κ. However, the cost of the alloy needs to be significantly lower than the cost of an iron-based alloy with about 32% nickel and 5% cobalt. The object of the present invention is to provide a low-expansion iron-nickel alloy, which uses an inexpensive alloy element to achieve an optimal thermal expansion coefficient in a temperature range of 2 (M00X :), and which can be used for different applications.
