2.0550 - CuZn37Mn3Al2PbSi - CuZn40Al2 sheet, strip, pipe

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe, sheet, tape, which are made of brass CuZn37Mn3Al2PbSi (2.0550) and CuZn40Al2. The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

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.

Chemical composition

In accordance with the technical requirements of DIN EN 17660, these alloys include (numerical data — in percentages):

Brand brass Copper Aluminum Zinc Manganese Silicon
CuZn37Mn3Al2PbSi 57… 60 1.3… 2.3 rest 1.3… 3.0 0.3… 1.3
CuZn40Al2 59… 61 1.8… 2.0 Not more than 0,3 -

In the brass considered, the presence of iron (up to 0.5.1.0%), tin (up to 0.4%) and nickel (up to 0.1%) is allowed.
