CuBe2Bi lead free
CuBe2Bi--- The Free lead, Free Cutting Beryllium Copper is identical to a version of lead-containing alloy C17300 and achieves the same exceptional strength after hardening, most importantly, the CuBe2Bi is to provide the same tailored for automatic machining operations as C17300 and promotes formation of finely divided chips thus extending cutting tool life.
Since European Union has been attaching great importance to the lead limits on every industry, in order to develop more and more industry purpose for the beryllium copper alloys, The CuBe2Bi was a newly developed grade after some of the experimental test and it is proved to be workable on the bulk trial production.
