EN AW-AlCu6BiPb(DIN 3.1655,AA2011,FC1,A92011,AU5PbBi) alloy is the most often selected for high speed automatic lathes. It offer the following advantages:
easy machining with any equipment;
cutting stress lower than most of other alloys;
longer life of cutting tools;
cutting area always clean due to very thin chip;
high mechanical properties;
possibility to anodize finished part in several colours.
Main applications
Screws, bolts, nuts, threaded bars.
