Cu-Al Alloys (Al Bronze)

Extensive fields in railroad engineering, in particular in overhead-line technology, have been changing from traditional sand casting to gravity die casting in recent years. The advantages relative to dimensional accuracy and surface quality speak for themselves and they permit an economical production because mechanical processing can often be minimize or even eliminate.

In addition to high strength characteristics, which correspond to those of steel, this group of materials also exhibits outstanding resistance to corrosion, erosion and cavitation. CuAl10Fe5Ni5-C or CuAl10Ni also possess good resistance to abrasion and good fatigue characteristics and thus they can be use for large static and dynamic loads.

Field of Use:

  • In catenary systems / rail technology, for example in overhead line construction as a spacer, for cable clamps and suspension cable holders, as locking parts for door systems, and much more.
  • In pump construction as pump, suction and pressure housings, for bucket wheels, segment sockets and stage casings, and much more.
  • In mechanical engineering for parts requiring high fatigue strength.
  • In boat building for saltwater-resistant applications where very high strength values are required.

Application examples:

  • Spacers
  • Holding pistons
  • Closing parts for doors
  • Forked connections
  • Contact line end terminals
  • Locking plates
  • Suspended-wire holders
  • Clamping pieces
  • Pump housings
  • Propellers
  • Suction caps
  • Segment supports
  • Control disks
  • Pressure caps
  • Step housings
