Technical specifications
Copper-zinc alloy of the brand CuZn37 (the closest analogue — alloy 2.0321) refers to the so-called «yellow» (or «golden») brass. This brass has good corrosion resistance and plastic deformability. Unlike other alloys, it can not be hardened after heat treatment. Therefore, the change in the mechanical characteristics of the alloy can be performed only as a result of hot and semi-hot stamping, during which the material is significantly strengthened, and the structure becomes finer, which increases the degree of anisotropy of the properties.
Urgency of application
CuZn37 (2.0321) brass is used for the manufacture of gear-type parts, various fasteners, manufactured by the technologies of both machining and stamping, printing rolls, springs, various construction products of decorative use, sliding bearings, guide valves, transmission parts of industrial equipment, piston rings, valves and tube heat exchangers, synchronizer rings, and the like.
Chemical composition
The composition of brass CuZn37 (2.0321) in accordance with the technical requirements of the DIN CEN TS13338 standard includes:
| Element | Cu | Al | Fe | Ni | Pb | Sn | Zn | Other impurities |

Assortment and application features
The sheet and tape from brass of the brand CuZn37 (2.0321) are produced in a wide range of sizes, cross-sectional areas and length. The workability increases with the temperature of the workpiece. When machining on metal cutting machines, large feed rates should be avoided due to the release of a significant amount of heat. The ability to weld and solder is good.
