Wire, round, rod l96 - 2.0220 - CuZn5

Wire, round, rod l96 - 2.0220 - CuZn5

Supplier — AvekGlob Company — offers wire, rod and wheel made of brass L96 (2.0220, CuZn5) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

The deformable brass of grade L96 (the nearest foreign analogues — alloys 2.0220 and CuZn5) is a highly plastic copper-zinc alloy, characterized by good electrical conductivity, not much inferior to copper. According to ASTM specifications, this alloy is called C21000. The brass in question is best known for its high resistance to corrosion. It is often used in the manufacture of coins and tokens, as well as in the manufacture of wrenches, where corrosion is a key factor. The alloy is well suited for forming operations of cold forming, so rolling profiles are often used as semi-finished products. Reducing the zinc content reduces the risk of stress corrosion cracking.

Urgency of application

Optimum use of brass of the brand L99 (2.0220, CuZn5) — manufacture of stamped parts: connectors, spring contacts and springs themselves, bushings and plain bearings, metal hoses, various components of equipment for the pulp and paper industry, ship and hardware production, used in general engineering and electrical industry.

Chemical composition

The composition of brass grade L96 must comply with the technical requirements of GOST 15527−2004 (numerical data — in percent):

Fe P Cu Pb Zn Sb Bi Impurities
up to 0.1 up to 0.01 95 — 97 to 0.03 2.66−4.8 up to 0.005 up to 0.002 only 0.2

Physical and mechanical properties

  • density, kg / m 3 — 8850;
  • melting point, 0 С — 1070;
  • coefficient of thermal expansion in the temperature range 20… 100 0 С, μm / deg — 17;
  • Specific heat, J / kggrad — 389;
  • coefficient of thermal conductivity at room temperature, W / mgrad — 245;
  • hardness in Brinell, HB — 50… 115 (respectively for soft and hard brass);
  • permissible compression stress, MPa — 220… 340 (respectively, for soft and hard brass);
  • yield strength, MPa — 90… 140 MPa (respectively, for soft and hard brass);
  • Modulus of elasticity, GPa — 110;
  • permissible tensile elongation,% — 55… 6 (respectively for soft and hard brass).

Assortment and application features

Brass bars, tape and wire from the material in question are produced in a wide range of sizes and profiles. Foreign analogues are produced in a range that meets the requirements of DIN EN 1652, 12163 and 12166, the range of Brass L90 is determined by GOST 10666−90 and GOST 2060−2007.

Brass grade L96 (2.0220, CuZn5) is well suited to all form-changing operations of cold stamping with high degrees of deformation. Hot stamping of the alloy is not recommended. Mechanical machinability is satisfactory, the ability to weld and solder is good, machining is difficult due to metal adherence to the cutting tool.

Supplier — AvekGlob Company — offers to purchase wire, circle or rod from brass L96 (2.0220, CuZn5) in a wide assortment of sizes and profiles. 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.
