The present invention relates to improvements in alloys used as materials for rayon-based and acrylic-based fiber spinning nozzles. Conventionally, gold-platinum (30 to 50% by weight (hereinafter abbreviated as "w/o")) alloy has been frequently used as a material for the above-mentioned rayon-based and acrylic-based fiber spinning nozzles. This alloy is thin sheet, drawn, and
Although it has excellent pore processability, the abrasion resistance and pressure resistance after aging treatment are low, so when used as a finished product, the edge of the spun surface side of the discharge hole may be reduced or damaged due to wear. It had the disadvantage of doing things like that. The present invention has been made in order to eliminate the above-mentioned drawbacks, and it is an object of the present invention to provide an alloy for spinning nozzles that has excellent workability, wear resistance, acid resistance, alkali resistance, and especially hardness after age hardening. It is. The alloy for spinning nozzles according to the present invention is platinum 65←
It has age hardening properties and is composed of 95 w/o, indium 2 to 20 w/o, and the balance palladium. The reason for adding indium to the alloy for spinning nozzles according to the present invention is that it can be heated to a solid solution region,
This is because, after performing solution treatment by rapid cooling, it exhibits remarkable age hardening properties when aged at an appropriate temperature. 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 the intermetallic compound of platinum and indium increases, resulting in poor workability. Moreover, the reason for adding palladium is to prevent the acid resistance and alkali resistance from decreasing due to the addition of indium. The composition of platinum
The reason why the range is 65 to 95 w/o is that if it exceeds 95 w/o, the amount of palladium added to tin will be small and local corrosion will easily occur, and if it is less than 65 w/o, the amount of palladium added to platinum will be too large, resulting in poor acid resistance. This is because alkali resistance deteriorates. 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. 3 and the alloy for spinning nozzles of Conventional Example No. 4 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.

きる画期的なものと言える。[Table] The abrasion resistance test was conducted using a nozzle 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 compared to conventional alloys for spinning nozzles, and is equivalent to conventional alloys for spinning nozzles in terms of workability and acid and alkali resistance. It can be seen that it has excellent properties and wear resistance. 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.
It can be said to be a revolutionary product that can replace conventional alloys for spinning nozzles.
