Technical characteristics

Bronze Br АЖ9−4 with an increased content of aluminium is among the most common bezolovni wrought bronze. It is used for the manufacture of air conditioners, refrigerators, other household appliances, plumbing systems and sewage systems for the manufacture of shut-off and distribution valves, water heaters, oil heaters, etc. Due to their high strength and resistance to corrosion is used for making valves, gears, bushings sliding bearings in the nodes of engineering and aviation. When operating on the surface of the material forms a strong oxide film, hindering the development of corrosion processes in liquid and gaseous media.
