About the product

From consideration for the environment, Showa Denko has developed the lead-less free-cutting alloy G23 as a replacement for the conventional free-cutting alloy with Pb (A2011 equivalent: G21). This G23 alloy uses Sn, Bi instead of the Pb, Bi used in conventional free-cutting alloys, to achieve a cutting process ability and surface treatment ability that are equivalent to or better than conventional free-cutting alloys (A2011 equivalent: G21).

Characteristics

  • G23 is Pb free, but retains a cutting characteristic that is equivalent to or better than A2011 material (G21).  
  • G23 has the same surface treatment performance as A2011 (G21).

Application

  • For cutting processed parts such as machine parts.
