Exclusive agent for PL, RO, HU, CZ, SK
2024 aluminium bars
This alloy has high mechanical properties and excellent resistance to fatigue. During machining, it creates quite long chips, therefore it is not well suited for automatic lathes. It can be replaced by 2030 which has the same mechanical properties but has better machinability, allowing higher productivity.
USA Red
According to EU directives: 2000/53/CE (ELV) - 2002/95/CE (RoHS)
Main applications
high structural resistance components for aviation, defence, high resistance components, screws and bolts.
