CuZn28Sn1 - C44300 sheet, strip, pipe
Supplier — AvekGlob company — offers at reasonable prices from the manufacturer a sheet, tape, pipe, made of brass CuZn28Sn1 (C44300). The supplier guarantees the timely delivery of products to any address specified by the consumer /
Copper-zinc alloy of the brand CuZn28Sn1 (other designation — C44300) — brass, which has an increased percentage of tin. It belongs to the group of the so-called. «Admiralty» brass, and has good corrosion resistance in chloride-containing media, which, due to the presence of nickel, is retained when the alloy is heated to temperatures of 250… 300 0 C. The alloy exhibits weak ferromagnetic properties.
Urgency of application
Typical products that are made of brass CuZn28Sn1 (C44300) — plugs for condensers and heat exchangers, evaporator circuit casings, purge heat exchanger boilers, air coolers, condenser seals, steam ejectors of turbines, oil coolers, parts for heating oil and compressed air, bushings pumping units of oil wells, etc. This brass is also used in marine, electrical (connectors, contacts) and nuclear industry.
The composition of brass of the brand CuZn28Sn1 (C44300) in accordance with the technical requirements of the ASTM B151 and DIN EN 17660 standards includes:
Copper (70… 73%);
Tin — 0,9… 1.2%;
Iron — up to 0,07%;
Nickel — up to 0.06%;
Zinc (3… 4%);
Impurities (aluminum and arsenic, with a total content of not more than 0.1%).
The industrial purity of copper used in the production of this alloy is not less than 99.6%.
