Casting alloys

Walcownia Metali Nieżelaznych „ŁABĘDY”offers casting alloys such as casting brasses, casting bronzes and ingots of copper and copper alloys. All casting alloys are manufactured according to PN, EN, DIN standards or to meet individual requirements specified by the contractor.

WHAT IS THIS

Casting bronzes

These are multi-component alloys containing tin and elements such as zinc, aluminium, lead and phosphorus.

The casting bronzes have a grainy structure. As is the case for casting brasses, they show resistance to corrosion and abrasion, as well as excellent castability and machinability.

The casting bronzes are divided as follows:

  • aluminum-iron bronze – BA93 (CuAl9Fe3),

  • aluminum-iron-manganese bronze – BA1032 (CuAl10Fe3Mn2),

  • tin bronze – B10 (CuSn10),

  • tin-phosphor bronze – B101 (CuSn10P),

  • tin-zinc bronze – B102 (CuSn10Zn2),

  • tin-lead bronze – B1010 (CuSn10Pb10) and B520 (CuSn5Pb20),

  • tin-zinc-lead bronze B555 (CuSn5Zn5Pb5), B663 (CuSn6ZnPb3) and B476 (CuSn4Zn7Pb6),

  • silicon-zinc-manganese bronze – BK331 (CuSi3Zn3Mn).

Like in the case of bronzes for plastic forming, they are used in the chemical, electromechanical, automotive and electrical industries.

WHAT IS THIS

Casting brasses

These are multi-component alloys that contain numerous alloying elements that deteriorate plastic properties, but at the same time improve strength and technological properties (e.g. castability, machinability). They are usually biphasic a + b’ and have a high content of Zn and other additives.

Casting brasses from our portfolio are resistant to abrasion, corrosion, cavitation and elevated temperatures up to 230°C. They are used in the chemical, construction, shipbuilding and transport industries for ship propellers, bearings, fittings and machine parts.
