いＳｉの含有範囲は６．５〜１０．５ｗｔ％である。First, to explain the significance of adding each element in the alloy of the present invention and the reason for its limitation, Si (silicon) improves wear resistance and strength by existing as Si particles in the alloy, but if less than 5 wt% However, the effect is lacking. On the other hand, if the content exceeds 13 wt%, problems such as decreased machinability will arise. Therefore, Si is 5 to 13
It must be contained within a range of wt%. A particularly preferable Si content range is 6.5 to 10.5 wt%.

If it exceeds this amount, coarse crystallized substances will be produced and the mechanical properties of the alloy will deteriorate. Therefore, Cu must be contained in a range of 2 to 7 wt%. A particularly preferable range of Cu is 2.5~

It is an element necessary to crystallize i, etc., and has the effect of improving the wear resistance and strength of the alloy. However, if it is less than 6 wt%, it is difficult to disperse a sufficient amount of the intermetallic compound, and the effect of improving wear resistance etc. is poor. On the other hand, if the content exceeds 12 wt%, this will lead to a decrease in extrudability and a decrease in ductility.

As a result, in addition to the wear resistance improvement effect of the Si particles, the wear resistance improvement effect of the hard Al-Ni intermetallic compound acts synergistically, resulting in excellent wear resistance. becomes. Further, it is preferable that Si is dispersed in a state in which the average particle size is smaller than the average particle size of the primary Al-Ni intermetallic compound. The reason for this is that when the average particle size of Si is larger than that of the primary Al-Ni system, processability such as machinability is reduced. The average particle diameter of Si and the average particle diameter of the primary Al-Ni intermetallic compound are not particularly limited, but in order to exhibit an even more excellent effect of improving wear resistance, the average particle diameter of Si should be 1 to 10 μm. It is preferable that the average particle size of the primary Al-Ni intermetallic compound is defined to be 5 to 50 μm.
