Pipe, bushing - 2.0402 - CuZn40Pb2 - C38010
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a pipe, bushing, which are made of brass CuZn40Pb2 (2.0402, C38010). The supplier guarantees the timely delivery of products to any address specified by the consumer.
The copper-zinc alloy of the brand CuZn40Pb2 (other names — 2.0402, C38010) 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. The increased lead content, however, leads to an increase in the degree of toxicity of the alloy, and therefore its use in the food and pharmaceutical industries, as well as for the purposes of drinking water supply is not recommended. Brass CuZn39Pb3 (2.0401, C38500) refers to alloys of universal use, having approximately the same machinability of cutting and pressure. The distinctive ability is the ability to withstand the corrosive phenomena that occur at cryogenic temperatures.
Urgency of application
From the brass of the brand CuZn40Pb2 (2.0402, C38010), products are produced that operate under conditions of intense sliding friction, and with constantly changing external operating temperatures, down to negative ones. These include gears of external mechanical gears, bearings, propellers and other rotary parts of sea vessels, elements of external decorative fences of buildings.
In accordance with the technical requirements of DIN EN 17660, this alloy contains:
Copper — 57… 59%;
Lead — 1,2… 2,0%;
Silicon — up to 0,2%;
Tin — up to 0.3%;
Zinc is the rest.
Other admixtures (bismuth, antimony, phosphorus) should not exceed in total 0.7%.
