Wire, round, rod 2.0220 - CuZn5 - C21000
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a circle, bar, wire, made of brass CuZn5 (C21000, 2.0220). The supplier guarantees the timely delivery of products to any address specified by the consumer.
Low-alloyed copper-zinc alloy of the brand CuZn5 (the nearest analogues are C21000, 2.0220) — brass, which has good working capacity, sufficient hardness, corrosion resistance and attractive appearance (golden color). This brass is part of the alpha-brass group, and has a homogeneous crystalline structure. Brass CuZn5 (C21000, 2.0220) is highly ductile, and can undergo cold forming to a significant degree of deformation without loss of strength. With the help of different heat treatment modes it can change its mechanical parameters.
Urgency of application
Typical applications: electrical industry, general engineering, construction and architecture, defense industry (sleeves) and other industries. From brass of mark CuZn5 (С21000, 2.0220) let out industrial valves of hydraulic installations, the industrial connecting armature working in corrosion-active environments, medium-loaded bearings of sliding. The material is also used in jewelry and for the coinage of coins, tokens, etc.
The composition of brass CuZn5 (C21000, 2.0220) in accordance with the technical requirements of the standard DIN EN 17660, includes:
Copper (94… 96%);
Zinc (3… 4%);
Impurities (bismuth, aluminum, tin, with a total content of not more than 0.1%).
