The present invention relates to improvements in alloys used as materials for rayon-based and acrylic-based fiber spinning nozzles. Conventionally, a gold-platinum (30 to 50% by weight (hereinafter referred to as "W/O") alloy) has been frequently used as a material for the above-mentioned rayon-based and acrylic-based fiber spinning nozzles. The former has excellent thin plate, drawing, and fine hole processability, but its wear resistance and pressure resistance after aging treatment are low, so when used as a finished product, the edge of the spun side of the spout hole may be damaged due to wear. The present invention has been made to solve the above-mentioned drawbacks, and has improved workability, wear resistance, acid resistance, alkali resistance, and especially hardness after age hardening. The present invention aims to provide an alloy for spinning nozzles with excellent properties.
It has age hardening properties and consists of 95 W/O tin, 2 to 20 W/O, and the balance being palladium. The reason why tin is added to the alloy for spinning nozzles according to the present invention is that, as is clear from the platinum-tin binary phase diagram, tin exhibits a maximum solid solution amount of 8 W/O with respect to platinum at 1365°C. This is because the solid solubility gradually decreases as the temperature decreases, and when the material is subjected to solution treatment in which it is heated to a solid solution region and rapidly cooled, and then aged at an appropriate temperature, it exhibits remarkable age hardening properties. If the amount added is less than 2 W/O, there is little improvement in hardness, and if it exceeds 20 W/O, the amount of intermetallic compound of platinum and tin increases, resulting in poor workability. Also, the reason for adding palladium is
This is to prevent a decrease in acid resistance and alkali resistance due to the addition of tin. The composition of platinum was set to 65 to 95W/O.
This is because when it exceeds 0, the amount of palladium added to tin is small and local corrosion tends to occur, and when it is less than 65 W/O, the amount of palladium added to platinum is too large and acid resistance and alkali resistance deteriorate. Examples and conventional examples will be described below in order to clarify the effects of the alloy for spinning nozzles according to the present invention. Hardness after solution treatment, workability, hardness after aging of the alloys for spinning nozzles of Examples No. 1 to No. 9 and the alloy for spinning nozzles of Conventional Example No. 10 having the component compositions shown in Table 1,
When tested for abrasion resistance, acid resistance, and alkali resistance, the results shown in Table 2 were obtained.

のできる画期的なものと言える。[Table] The wear resistance test was conducted using a spinning nozzle with 70 discharge holes with an inner diameter of 50 μm and a corner radius of curvature of 5 μm, after spinning rayon fiber at a pressure of 10 kg/cm 2 for 2000 hours. I turned over and went. As is clear from the above, the alloy for spinning nozzles according to the present invention has significantly superior hardness after age hardening and wear resistance compared to conventional alloys for spinning nozzles, and has better processing, acid and alkali resistance than conventional alloys. It can be seen that this alloy is excellent as well as the alloy for spinning nozzles. As detailed above, the alloy for spinning nozzles according to the present invention has extremely excellent workability, acid resistance, alkali resistance, especially hardness after age hardening, and wear resistance, so it is superior to conventional alloys for spinning nozzles. It can be said to be an epoch-making product that can be replaced.
