    SummaryOverviewPhase diagram

    Tellurium is usually added to copper to improve machinability ("free cutting"). ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved whilst electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper, whilst machinability is similar to brass - the alloy's hardnesses are increased by precipitation of copper telluride .
