Aluminium bronzes

ALCARO® - aluminium bronzes

ALCARO materials are heterogeneous aluminium multi-alloy bronzes. At an aluminium content between 8% and 12.5%, nickel and iron are added. This improves corrosion resistance in aggressive media.

The aluminium bronze has above-average mechanical and physical properties which are particularly valuable for mechanical engineering, shipbuilding and apparatus engineering.


  • High tensile strength and fatigue strength with high toughness
  • Good corrosion resistance to neutral, acidic, aqueous solutions as well as water
  • Good resistance to scaling, erosion and cavitation
  • Good thermal and electrical conductivity
  • Good sliding properties at low sliding speeds with high loads
  • Cost-saving through small machining allowances/ hardly any scrap

Special applications

  • Mould and die production
