When the swash plate 1 is rotated, the piston 2 reciprocates, and as a result, the refrigerant gas sealed inside is sucked into the cylinder bore 3 and compressed. The swash plate 1 is fixed to shirts I to 5 which are rotatably supported by a cylinder block 4, and the piston 2 is moored to the swash plate 1 via a shoe 6 and a ball 7. When the swash plate 1 is rotated integrally by the shirt 1-5, the shoes 6 slide on the sliding surface of the swash plate 1 and move the outer circumference of the swash plate 1 in the axial direction via the balls 7. The structure is such that the signal is transmitted to screws 1 to 2. Such swash plate compressors are used in car coolers.

る。In the swash plate compressor used in the above car cooler, the part exposed to the most severe sliding conditions is the sliding part between the swash plate 1 and the shoe 6 shown in FIG. The sliding speed is about 2 to 3 m/sec when the engine is idling, 20 to 25 m/sec at about 600 rpm at maximum rotation, and about 7 to 15 m/sec even during normal running.

The present inventors have conducted various research and development, and as a result, the thermal conductivity has been strengthened to the extent that it does not decrease too much, and We have developed a sliding material that has good sliding properties, with little decrease in hardness, especially at high temperatures. The gist is that Ni is 0.4 to 4.0 wt%, Si is 0.1 to 1.

It is an element that precipitates as an intermetallic compound such as i and strengthens 1.

てはなじみ性を重んじるよりも熱伝導性を良くし、効果
的に熱を放散させることおよび高温下で硬度の低下を少
なくして組織変化を少なくすることがシューのすベリ性
能を改善する上で有効である。In sliding parts where the amount of lubricating oil is small, the most important issue is the thermal conductivity of the sliding members. For this reason, for shoe materials, rather than focusing on conformability, it is important to improve thermal conductivity, effectively dissipate heat, and reduce the decrease in hardness at high temperatures to minimize structural changes. It is effective in improving
この意味において、熱伝導率をあまり低下させず、強度

合金が有効なのであり、これによって強靭で焼付きにく
い優れた摺動材料を得ることができる。In this sense, precipitation-hardening Cu-Ni-8i alloys that improve strength without significantly reducing thermal conductivity are effective, and this makes it possible to obtain excellent sliding materials that are tough and resistant to seizure. Can be done.

このような望ましい硬度を有している。It has also been found that the hardness of the sliding material used for the shoe of a swash plate compressor for a high-performance car cooler is desirably 80 or higher (Vickers hardness Hv) at a high temperature of 300°C. All sliding materials have such desirable hardness.
ここにおいて、本発明に従ってCuに添付される元素の
それぞれの添加量は、次のことを考慮して定められる。Here, the amount of each element added to Cu according to the present invention is determined in consideration of the following.

強度を向上させるためであるが、0゜001wt%未満
ではその効果はなく、3.0wt%を超えると熱伝導率
が低下するためである。That is, first, Ni is co-added with Si in Cu, and by performing solution treatment and aging treatment, it precipitates as intermetallic compounds such as Ni and Si, and is an element that improves strength without reducing thermal conductivity. However, the reason for adding 0.4 to 4.0 wt% is that if it is less than 0.4 wt%, no improvement in strength will be observed, and if it exceeds 4.0 wt%, thermal conductivity and workability will deteriorate. be. Si is also an element that improves strength without reducing thermal conductivity by co-adding with Ni and precipitating as an intermetallic compound;
The reason for adding 0 wt% is that if it is less than 0.11 wt%, no improvement in strength will be observed, and if it exceeds 1.0 wt%, the thermal conductivity will be significantly degraded. Preferably Ni, Si
The ratio of the amounts added is preferably (Ni/5i)=(4/L), which is close to the composition of the intermetallic compound (Ni, Si). Furthermore, as subcomponents, Zn, P, Sn, λs, Cr, Mg, Mn-

, Ag, Pb, B, and one or more lanthanoid elements in an amount of 0.001 to 3. Adding Owt% is
This is to improve the strength, but if it is less than 0°001 wt%, there is no effect, and if it exceeds 3.0 wt%, the thermal conductivity will decrease.

用銅合金であることがわかる。○: No abnormality Δ: Partial seizure ×; Seizure XX: Deformed or worn during the test. As can be seen from these tables, the alloy of the present invention is a very good copper alloy for sliding materials that does not generate heat, soften, deform, wear, or seize even when used in the shoes of swash plate compressors. I understand that.
