Light balls featured by good corrosion and wear resistance, very good surface finishing.
1000 series alloys are not heat treated. Balls can be provided in the passivated conditions.
2000 series alloys allow to get better mechanical characteristics. Balls can be provided in the passivated condition.
3000 series alloys are not heat treated and show slightly better mechanical characteristics with respect to series 1000. Balls can be provided in the passivated state.
5000 series alloys are not heat treated and feature a good workability.
6000 series alloys thanks to Si and Mg addition, are heat treatable. They feature mechanical properties slightly lower than series 2000 and 7000.
7000 series alloys are heat treated and show the best mechanical properties between aluminium alloys. Balls can be provided in the passivated state.
Special bearings and valves, sealing elements (crushed balls), they are used in automotive industry(safety devices), shipbuilding industry, aviation and aerospace industry, electronic industry, military fields and in welding processes.
