Wire, round, rod 2.0321 - CuZn37

Supplier — AvekGlob Company — offers wire, bar, rod made of brass CuZn37 (2.0321) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

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.

. Actuality of use

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
Minimum content,% 62.0 - - - - - 35.25 -
The maximum content,% 64.0 0.05 0.1 0.3 0.1 0.1 38.0 0.1

Physical and mechanical properties

  • density, kg / m 3 — 8420;
  • melting point, 0 С — 902… 920;
  • coefficient of thermal expansion in the temperature range 20… 300 0 С, μm / deg — 21;
  • Specific heat in the temperature range 20… 300 0 С, J / kggrad — 404;

  • limit of temporary resistance, MPa — 350… 490 (respectively, for soft and hard brass);
  • yield strength, MPa — 210… 300 (respectively, for soft and hard brass);
  • permissible tensile elongation,% — 38… 8 (respectively, for soft and hard brass).

Assortment and application features

The circle, wire and brass of CuZn37 (2.0321) are produced in a wide range of sizes, cross-sectional areas and lengths. 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 — good.

Supplier — AvekGlob company — offers to purchase wire, circle or rod, which are made of brass of the brand CuZn37 (2.0321). Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
