Standard lengths: ca. 3000 mm, 2000 mm, 1000 mm and 500 mm.

Our foundries are able to centrifugally cast (flanged) tubes in any size, up to a diameter of Ø 2000 mm and length up to 3000 mm in all current alloys.

On request:

  • Finished machined components to your requirements
  • Pattern casting
The given weights are theoretical.

The machining allowance on the finished sizes is sufficient for lengths < 250 mm.

For finished part lengths > 250 mm - especially diameters > 172 mm - a higher machining allowance is necessary

Characteristics Corrosion and seawater resistance, high wear resistance suitable even at high sliding speeds. Better mechanical values than RG7 because of a higher content of tin and less content of lead and zinc. Because of that the dry running properties and the machinability are not as good as for RG7. Typical use: bearings with high sliding speed, heavy duty worm wheels and spindles.

Characteristics CuSn12Pb has in comparison with CuSn12 better dry running properties due to its lead content. Typical use is often where the dry running properties of RG7 are necessary, and the mechanical values of CuSn12 are needed. CuSn12Pb offers in this context a nice solution between those two alloys.
