C18700 Free-machining Copper Bar
Specifications:ASTM B301, B249
Delivery condition: Heat treated and cold worked
C18700 copper is a low alloyed high conductivity lead-copper for free cutting applications. It has a moderately low melting temperature among wrought coppers and low tensile strength and ductility. The C18700 copper alloy has been widely used for where require high mechanical properties and deformation resistance at high temperature such as: electric connectors, motor and switch parts, screw machine parts requiring high conductivity.
