Description

Bronze БрА10Ж4Н4 used: for the manufacture of semi-finished pipes and long products (bars); tube plates of condensers, extruded pipes; parts of chemical equipment.

Note

Bronze badly deformed in the cold state, is deformed in the hot state, has high strength at elevated temperatures, corrosion resistance, high erosion and cavitation resistance.
Analog bronze БрА10Ж4Н4 (Brazhn10−4-4) at the CMEA 377−76 is bronze CuAl10Fe4Ni4.
