摘要：
A mixed metallurgical powder is provided containing powdered copper used for the manufacture of sintered structural parts such as brushes. A sintered compact made of the mixed metallurgical powder and a method for the manufacture of the sintered compact are also provided. The powder and the sintered compact are provide with an extremely high corrosion resistance because, preferably, the mixed metallurgical powder contains powdered copper and 20-400 ppm by weight of Bi in the form of powdered Bi.
