  • Sliding part made of Pb-free Cu-Bi based sintered alloy
    Patent number: 8993493
    Abstract: Sliding parts are made of Pb-free Cu—Bi based sintered material. The side in contact with a shaft is machined to a predetermined roughness. A number of Bi phases are present on the finished surface. Stable performance of Bi is to be exhibited. Machined sintered material covers a portion of the Bi phases. The ratio of the exposed surface area of the Bi phases is 0.5% or more relative to the area of the finished surface.
    Type: Grant
    Filed: September 9, 2009
    Date of Patent: March 31, 2015
    Assignee: Taiho Kogyo Co., Ltd.

  • Lead-free copper-based sintered sliding material and sliding parts
    Patent number: 8845776
    Abstract: The present invention relates to sliding material provided by sintering a lead-free copper or copper alloy and contains at least one mineral selected from the group consisting of talc, mica, kaolinite mineral and montmorillonite mineral. Pb has conventionally been included in sliding materials for the purpose of obtaining conformability and seizure resistance. Despite the absence of Pb, the Pb-free copper-based sliding material and sliding parts according to the present invention have improved sliding properties.
