Wire, round, rod 2.0550 - CuZn37Mn3Al2PbSi - CuZn40Al2
Supplier — AvekGlob company — offers wire, bar and rod, which are made of brass CuZn37Mn3Al2PbSi (2.0550) and CuZn40Al2 at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Copper-zinc alloys of CuZn37Mn3Al2PbSi (2.0550) and CuZn40Al2 grades refer to aluminum brass, and brass CuZn37Mn3Al2PbSi is additionally doped with manganese, lead and silicon, which significantly increases the strength of the alloy, while reducing its plasticity. Both considered alloys are characterized by high wear resistance and good working capacity, with sufficient machinability and corrosion resistance. Brass is characterized by good ductility in the hot state, when pressed, increase its mechanical performance. Alloys exhibit weak paramagnetic properties.
Urgency of application
Aluminum brass grades CuZn37Mn3Al2PbSi (2.0550) and CuZn40Al2 are used for the manufacture of components of mechanical transmissions and machine parts: synchronizer rings and guide valves in cars, conveyors, and other mobile systems, as well as for obtaining structural support elements operating in environments with high humidity. Alloys are also used in construction and in the manufacture of sliding bearings.
In accordance with the technical requirements of DIN EN 17660, these alloys include (numerical data — in percentages):
