2.0220 - CuZn5 - C21000 sheet, strip, pipe

Supplier — AvekGlob company — offers at reasonable prices from the manufacturer a sheet, tape, pipe, made of brass CuZn5 (C21000, 2.0220). The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

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. Used in jewelry and for coinage, coins, etc.

Chemical composition

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%).

Physical and mechanical properties

  • density, kg / m 3 — 8550;
  • melting point, 0 С — 900… 940;
  • coefficient of thermal expansion in the temperature range 20… 100 0 С, μm / deg — 18,4;
  • coefficient of thermal conductivity at room temperature, W / mgrad — 125.6;
  • hardness in Brinell, HB — 45… 120 (respectively, for soft and hard brass);
  • allowable compression stress, MPa — 240… 450 (respectively for soft and hard brass);
  • yield strength, MPa — 50… 120;
  • modulus of elasticity, GPa — 104;
  • permissible tensile elongation,% — 45… 50.

Assortment and application features

A sheet, a tape, a pipe from a considered material are made in a wide range of the sizes, the areas of cross section and length. Mechanical machinability of the alloy — limited, weldability and solderability — good. Hot stamping is carried out in the temperature range 700… 800 0 С.

Supplier — AvekGlob Company — offers to purchase a sheet, tape or pipe, which are made of low-alloy brass of the brand CuZn5 (C21000, 2.0220). 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.
