[Industrial Application Field] The present invention relates to a material for a crystal resonator case, and more particularly to a sealed crystal resonator case material with excellent drawing properties. [Prior Art] Nickel silver such as 64Cu-18Ni-Zn has been mainly used as a material for the case of this type of sealed crystal resonator. Materials for sealed crystal oscillator cases must have excellent properties such as strength, drawing workability, corrosion resistance, stress corrosion cracking resistance, plating properties, and soldering properties. Of course, in addition, the base material Fe-29wt%Ni-17wt%
It is necessary to have excellent resistance weldability with Co or Fe-42wt%Ni. In addition, crystal resonators are electronic components and cannot be treated as an exception, and even the small components that make up the crystal resonators have been reconsidered from various aspects. The nickel silver used as the material for this crystal resonator case has excellent strength, drawing workability, Fe-42wt%Ni
Although it has excellent resistance weldability with other materials, it has drawbacks such as solderability, corrosion resistance, stress corrosion cracking resistance, and plating properties. In addition, nickel silver is generally horizontally continuously cast and then subjected to repeated cold rolling and annealing to form a plate material, making the process complicated and expensive. [Problems to be Solved by the Invention] The present invention solves the above-mentioned advantages of nickel silver, which has been conventionally used as a material for crystal resonator cases, such as high strength, excellent drawing workability, and excellent Fe.
-Cu-Ni-Sn has resistance weldability with 42wt%Ni, and has better solderability, corrosion resistance, stress corrosion cracking resistance, and plating performance than nickel silver.
The present invention provides crystal resonator case materials made of alloys and Cu-Ni-Sn alloys. [Means for Solving the Problems] The crystal resonator case material according to the present invention (1) contains 3.0 to 15.0 wt% Ni and 1.0 to 4.0 wt% Sn, with the remainder being free from Cu and unavoidable impurities. The first invention provides a material for a crystal resonator case characterized by: (2) containing 3.0 to 15.0 wt% of Ni, 1.0 to 4.0 wt% of Sn, and further containing 0.001 to 0.1 wt% of P; , Mg0.001~0.1wt%, B0.001~0.1wt%, Si0.001~0.1wt%, Cr0.001~0.1wt%, Ti0.001~0.1wt%, Zr0.001~0.1wt%, Al0 Contains one or more selected from the group consisting of .005-1wt%, Co0.005-1wt%, Fe0.005-1wt%, Mn0.005-1wt%, Zn0.01-1wt%, and A second material for a crystal resonator case, which contains selected components in a total amount of 0.001 to 1 wt%, with the remainder consisting of Cu and unavoidable impurities.
This invention consists of two inventions. The crystal resonator case material according to the present invention will be explained in detail. First, the components and component ratios of the crystal resonator case material according to the present invention will be explained. Ni is an essential element for improving strength, resistance weldability with base alloys such as Fe-42wt%Ni, and corrosion resistance.If the content is less than 3.0wt%, these effects are small, and If the Ni content exceeds 15 wt%, hot workability deteriorates and the price increases due to the increased Ni content. Therefore, the Ni content is set to 3.0 to 15.0 wt%. As is known in general phosphor bronze, Sn is an element that improves the strength and drawability as the content increases, but if the content is less than 1.0wt%, this effect is small, and if the content is less than 1.0wt%, If the content exceeds %, hot workability becomes difficult. Then,
The Sn content is 1.0 to 4.0 wt%. P, Mg, B, and Si are necessary elements as deoxidizers for Cu-Ni-Sn alloy molten metal, and their content is 0.001wt%.
If the P and Mg contents exceed 0.1wt%, this effect will be small.
Cu and low melting point eutectic Cu + Cu 3 P (melting point 714°C) and Cu + MgCu 2 (melting point 722°C) are formed, and hot workability at temperatures above 750°C deteriorates, and the content of B and Si decreases.
If it exceeds 0.1wt%, cracks are likely to occur during hot working. Therefore, the P content is 0.001~0.1wt%, Mg
Content is 0.001~0.1wt%, B content is 0.001~
0.1wt%, and the Si content is 0.001 to 0.1wt%. When the content of Cr, Ti, and Zr exceeds 0.001wt%, the structure of the ingot becomes finer, the hot workability is stabilized, and the strength is improved. If the content exceeds 100%, the molten metal will be easily oxidized and it will be difficult to obtain a healthy ingot. Therefore, the Cr content is 0.001-0.1wt%, the Ti content is 0.001-0.1wt%, and the Zr content is 0.001-0.1wt%.
%. Al, Co, Fe, and Mn have the effect of improving strength when the content exceeds 0.005wt%, and Zn has the effect of improving strength when the content exceeds 1wt%. If it exceeds the limit, solderability will deteriorate. Therefore, the Al content is 0.005-1wt%, the Co content is 0.005-1wt%, the Fe content is 0.005-1wt%,
Mn content is 0.005~1wt%, Zn content is 0.01~1wt
%. Note that, for the reasons explained above, the total content of one or more selected components is 0.001 to 1 wt%. [Example] Next, an example of the crystal resonator case material according to the present invention will be described. Example A copper alloy having the components and proportions shown in Table 1 was melted in the atmosphere under a charcoal coating in a Kryptor furnace, and cast to a thickness of 60 mm, a width of 60 mm, and a length of 180 mm.
mm ingot. The front and back sides are machined and the thickness is 10mm at a temperature of 850℃.
Hot rolling was carried out until then. Next, after pickling to remove oxide scale, cold rolling is performed to a thickness of 3.5 mm.
mm, annealed in an electric furnace at a temperature of 625°C for 1 hour, and oxidized scale was removed by pickling. Such a plate material is cold rolled to a thickness of 0.83mm.
After descaling by annealing at 625℃ for 1 hour, the thickness is
The sample was prepared with a final annealing of 0.50 mm and a temperature of 625° C. for 1 hour. In addition, as a comparative example, a commercially available nickel silver material with a thickness of 2 mm was cold rolled to a thickness of 0.83 mm, and the material was heated at 622°C.
After descaling by annealing for 1 hour at a temperature of
The samples were prepared by cold rolling to a thickness of 0.50 mm and final annealing at a temperature of 625° C. for 1 hour.

[Table] 1 to 15 of materials for crystal resonator cases according to the present invention
The mechanical properties and electrical conductivity in the rolling direction of the JIS No. 5 test piece of Comparative Example 16 are shown in Table 2. In addition, using an Erichsen drawing tester, a test piece with a blank diameter of 66 mmφ was tested with a wrinkle pressing force of 300 kg, lubricating oil (product name: Jiyeonson Wax), 3 parts water, a drawing speed of about 12 mm/sec, and a punch diameter of 33 mmφ to reduce the wrinkles by 50%. A drawing process was performed, and the selvage ratio was calculated as (H-h)/{(H+h)/2}×100. However, H is the average peak height and h is the average valley depth. The results are shown in Table 2. Solder wettability was determined by immersing a 0.5 mm thick, 25.4 mm wide, and 50.8 mm long test piece in the weakly active flux Alpha 611 in advance for 5 seconds in a 60Sn/40Pb eutectic solder bath at 230°C. The results of investigating the solder wetting conditions are shown in Table 2. Corrosion resistance was measured by exposure to saturated steam at 40°C containing 15 ppm SO 2 gas for 96 hours, and the results are shown in Table 2. Stress corrosion cracking resistance was tested according to DH Thompson's stress corrosion cracking test method. The dimensions of the test piece were 0.50 mm thick, 12.7 mm wide, and 150 mm long. The ends were tied together to form a loop-shaped test piece. After 24 hours, the knot was untied and the linear distance between the ends was measured. Using this value as the initial value, the ends were tied together again and exposed to steam in a 61 desiccator containing a solution of 11 diluted with 28% ammonia water and an equal amount of water at a temperature of 350°C. Then, the change in the linear distance of the end portion over time was measured, and the time required to reach 50% was measured, and the results are shown in Table 2. Since the plating property has a correlation with the solder wettability, the crystal resonator case material according to the present invention is good.
