Dalian Yiming Precision Machinery Co., Ltd. specializes in producing copper bushings, copper plates and copper alloy parts of ZCuAl10Fe3, also known as 9-4, ZQAl9-4.

Main chemical composition: aluminum Al: 8.5 ~ 11.0, iron Fe: 2.0 ~ 4.0, copper Cu: the rest.

Main use characteristics: ZCuAl10Fe3 cast copper alloy has high mechanical properties, good wear resistance and corrosion resistance, can be welded, is not easy to braze, and large-scale castings can prevent brittleness from air cooling at 700 °C. ZCuAl10Fe3 cast copper alloy is used for important castings requiring high strength, wear resistance and corrosion resistance, such as bushings, nuts, worm gears and pipe fittings working below 250 °C.
