Product Information
CuSn7Zn4Pb7 can be classified somewhere between tin and lead bronze and it is also known under the trivial name Rg7 or as red bronze. It is one of the most popular bronze alloys because it can be used in various machine parts. CuSn7Zn4Pb7 is a medium-hardness material and it works well under emergency conditions. It has very good machining, welding and soldering properties. It is used for bearings in various engineering branches, medium duty sliding plates and rails, piston pin bushes, connecting rods, gears, etc.
