Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe, bushing, which are made of brass CuZn39Pb3 (2.0401, C38500). The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Copper-zinc alloy of the brand CuZn39Pb3 (other names — 2.0401, C38500) contains an increased percentage of lead, which improves the mechanical machinability of the material, its corrosion resistance, and also contributes to a significant reduction in the coefficient of friction. The latter is used in the production of high-loaded sliding bearings. However, the increased lead content leads to an increase in the degree of toxicity of the alloy, so its use in the food and pharmaceutical industry, as well as for the purposes of drinking water supply is not recommended. Brass CuZn39Pb3 (2.0401, C38500) can not be subjected to heat treatment. However, it is possible to control the strength by selecting suitable plastic deformation modes, since the material is strengthened during the stamping process.

Urgency of application

Brass of the brand CuZn39Pb3 (2.0401, C38500) is considered to be the main alloy for manufacturing products by the methods of mechanical processing. Typical parts are cogwheels, swivel parts, hollow screws, corrosion resistant pipes and fittings.

Chemical composition

In accordance with the technical requirements of DIN EN 17660, this alloy contains:

Copper — 57… 59%;

Lead — 2.5… 3.5%;

Aluminum — up to 0,05%;

Nickel — up to 0,3%;

Iron — up to 0,3%;

Tin — up to 0.3%;

Zinc is the rest.

The amount of impurities should not exceed 0.2%.

Physical and mechanical properties

Assortment and application features

The tube and bush of brass CuZn39Pb3 (2.0401, C38500) are produced in a wide range of sizes and diameters. The material is perfectly processed on machine tools and automatic machines. When used, especially in ammonia-containing media under load, the problem of corrosion cracking of articles arises. Arc welding is not recommended. The temperature range of hot stamping is 700… 800 ⁰ С.

Supplier — AvekGlob Company — offers to buy a pipe or a brass sleeve of the brand CuZn39Pb3 (2.0401, C38500) in a wide range of cross sections and lengths. 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.
