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~
95 w/o, chromium 2 to 20 w/o, and the balance palladium, which has age hardening properties. The reason why chromium is added to the alloy for spinning nozzles according to the present invention is that it exhibits remarkable age hardening properties when aged at an appropriate temperature after being subjected to solution treatment in which it is heated to a solid solution region and rapidly cooled. be. 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 chromium increases, resulting in poor workability. The reason for adding palladium is
This is to prevent a decrease in acid resistance and alkali resistance due to the addition of chromium. Platinum composition 65~95w/
o is selected because if it exceeds 95w/o, the amount of palladium added to chromium will be small and local corrosion will occur easily, and if it is less than 65w/o, the amount of palladium added to platinum will be too large and acid resistance and alkali resistance will deteriorate. This is to do so. 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, workability, hardness after aging, and wear resistance after solution treatment 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. The results shown in Table 2 were obtained when tests were carried out for properties, acid resistance, and alkali resistance.

きる画期的なものと言える。[Table] The abrasion resistance test was conducted using a spinning nozzle with an inner diameter of 50 μm and a corner radius of curvature of 5 μm, after spinning rayon fiber for 2000 hours at a pressure of 10 kg/cm 2 . I went there. 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, has excellent wear resistance, and has excellent workability, acid resistance, and alkali resistance. It can be seen that this alloy is as good as the conventional 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.
It can be said to be a revolutionary product that can replace conventional alloys for spinning nozzles.
