る。The above-mentioned conventional hardened bushes made of steel and bushings made of gunmetal have the advantages of being inexpensive and having high strength, but have a high friction coefficient, and have problems of seizure resistance and abrasion resistance. In order to solve these drawbacks, the fact is that a forced lubrication is performed by forcibly supplying lubricating oil to a sliding portion with a partner shaft. By the way, in recent years, for the purpose of improving the environment and significantly reducing costs, it has been desired to use oilless or oil-impregnated bearings in bushes used for the above applications. The present invention has been made in view of the above circumstances, and provides a copper-based sintered bearing material having excellent sliding characteristics (low frictional resistance) and adhesion resistance, which can be used even under severe use conditions, and a method for producing the same. It is intended to provide.

大幅に向上することを見い出した。The present inventors have focused on a Cu-10Zn-7.5Sn based sintered alloy having good wear resistance and adhesion resistance, and have been working to strengthen the matrix of this alloy. When Al is added in an amount of about 5% by weight, high strength Cu
It has been found that a very hard Sn-Al alloy phase precipitates in a network form in the α-solid solution of -Zn-Al and exhibits a pearlite-like structure. Originally, Sn is an element constituting an α solid solution together with Cu and Zn, but it is considered that a part of the element was extracted from the α solid solution due to the presence of Al and was bonded to and precipitated with Al. However, this is merely an estimation, and it goes without saying that the present invention is not limited by the presence or absence of such an action. Further, the amount of Al added and the structure of the structure of the Sn-Al alloy phase are merely examples. The present inventors have further found that by dispersing graphite having excellent self-lubricating properties in the matrix, the sliding characteristics and abrasion resistance are significantly improved in combination with the strengthening of the matrix.

It improves the wear resistance of the alloy and the corrosion resistance to degraded oil. If the Zn content is less than 10%, such an effect becomes insufficient, and if the Zn content exceeds 30%, the alloy becomes brittle. Sn: 3 to 10% Sn forms a solid solution with Cu together with Zn to strengthen the matrix and improve the wear resistance of the alloy.

On the other hand, when the content of Zn is increased, the material becomes brittle due to the precipitation of the β phase, but by adding Al, the content of Zn can be reduced and the embrittlement can be suppressed. In addition, a part of Al forms a solid solution in the Cu-Zn matrix to form Cu-Zn-A
1 forms a solid solution, and partly combines with Sn and precipitates as a very hard Sn-Al alloy phase as described above. When the content of Al is small, the Sn-Al alloy phase is network-like, but as the Al content increases, the Sn-Al alloy phase increases.
The proportion occupied by the alloy phase increases and the alloy phase becomes lumpy. That is, A
As the content of l increases, the hardness of the matrix increases and the abrasion resistance improves. The content of Al is
If it is less than 2%, the above-mentioned effects are not sufficient, and 20%
