Cu-Sn based mixed powder and its production method

摘要

Sinterring the Cu-Sn based mixed powder and the Cu powder and the Sn powder which are used for the raw materials powder for metal ceramic which features that it consists of the mixed powder of the pulverized powder and the electrolytic copper powder of the Cu-Sn sintered body which is alloyed partly, production method of the Cu-Sn based mixed powder which is used for the raw materials powder for metal ceramic which features that it produces the Cu-Sn sintered body which it alloys partly, pulverizes this sintered body and the Cu-Sn pulverized powder profit, it mixes this Cu-Sn pulverized powder and the electrolytic copper powder next. Raw materials powder for metal ceramic of business such as oil-impregnated sintered bearing is produced at the time of, it raises compactibility such as green density and rattler value of the powder, improves sinterring quality such as pressure ring strength, furthermore cost it designates that the Cu-Sn powder which can reduce is obtained as topic.
