IMG_4554_副本.jpgBasic characteristics

The flange graphite bronze bushing is made of H62 brass material, and holes of appropriate size and order are arranged on the copper sleeve base, and graphite with lubricating properties is embedded in the holes,the outer ring of the bronze bushing is threaded.

H62 (that is, four or six brass). At room temperature, β phase is much harder than α phase, so it can be used for parts that bear larger loads. α + β two-phase brass can be hot-worked above 600 ℃. α + β two-phase brass microstructure: α is a bright white solid solution, β is an ordered solid solution based on CuZn.
