2.1183 - CuSn7Pb15 - C93800 sheet, strip, pipe

2.1183 - CuSn7Pb15 - C93800 sheet, strip, pipe

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet, pipe or tape made of bronze C93800 (2.1183, CuSn7Pb15). The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

Bronze brand C93800 (another name according to the DIN EN specification — CuSn7 Pb15 alloy, this material is also produced according to ASTM B505 and B271 under the name 2.1183) is a tin bronze alloyed with an increased amount of lead. This bronze is resistant to the phenomena of surface mechanical damage, structural homogeneity, increased resistance to shear stress, and low cost. Compressive strength is reduced, therefore under heavy operating conditions the material is not applied.

Urgency of application

Bronze grade C93800 (2.1183, CuSn7Pb15) is used for the manufacture of such products as heavy-loaded bearings, bushings (including centrifuges), gears, cogwheels, worm wheels, liners, piston rings, pump components and valves, sleeves, steam fittings. Areas of use are the production of sanitary fittings and weapons, general engineering, power and transport machine tools. It is not recommended for the manufacture of parts that are used in the food and pharmaceutical industries.

Chemical composition

In accordance with the above standards, the composition of this bronze includes the following elements (numerical data — in percent):

Fe Si Ni P S Al Cu Pb Zn Sb Sn
Not more than 0.15 Not more than 0.005 Not more than 1 Not more than 0,05 Not more than 0.08 Not more than 0.005 Rest 13−16 Not more than 0.8 Not more than 0.8 6.3 — 7.5

Notes. 1. Copper of chemical purity is used not less than 99.7%, while in copper, a partial content of nickel is allowed. 2. Nickel may contain traces of cobalt. In the production of rolled products, the percentage of phosphorus is up to 0.15.
