Provided is free cutting alloy excellent in machinability, preserving
various characteristics as alloy. The free cutting alloy contains: one or
more of Ti and Zr as a metal element component; and C being an
indispensable element as a bonding component with the metal element
component, wherein a (Ti,Zr) based compound including one or more of S,
Se and Te is formed in a matrix metal phase. The free cutting alloy is
more excellent in machinability, preserving various characteristics as
alloy at similar levels to a conventional case. The effect is especially
conspicuous, for example, when a compound expressed in a chemical form of
(Ti,Zr).sub.4C.sub.2(S,Se,Te).sub.2 as the (Ti,Zr) based compound is
formed at least in a dispersed state in the alloy structure.
