EN AW-AlCu6BiPb进口易切削高强度超硬铝合金

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 e;

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.
