2.0280 - CuZn33 - C26800 sheet, strip, pipe

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet, a ribbon pipe made of brass CuZn33 (C26800, 2.0280). The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Copper-zinc alloy of the brand CuZn33 (the nearest analogues — C26800, 2.0280) refers to the so-called «yellow» brass. It is used because of its good decorative qualities, mechanical strength and corrosion resistance. Good for various heat treatment regimes.

Urgency of application

This material is used in the following industries:

Construction and architecture (decorativeness, resistance to atmospheric corrosion);

Household appliances — heating systems, handrails, locks, grilles, protective screens (corrosion resistance, mechanical strength);

Industry: cisterns, medium-loaded friction parts of conveyors, sanitary fittings, electrical circuit components, fasteners, etc .;

Maritime: containers for liquids, superstructures for small vessels, chains.

Chemical composition

The composition of brass CuZn33 (C26800, 2.0280) in accordance with the technical requirements of the standard DIN EN 17660, includes:

Copper (64… 68.5%);

Zinc (30… 33%);

Impurities (lead, iron with a total content of not more than 0.14%).
