Copper Alloy C14700 | Copper Casting Manufacturing 

UNS C14700 sulfur bearing copper alloy has high corrosion resistance, free machining properties, and 90% minimum IACS conductivity. It is generally available in the form of wire and rod. C14700 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. In addition, C14700 has a moderately high thermal conductivity and comparatively low tensile strength. Among wrought copper alloys, the composition of C14700 copper is notable for including sulfur (S) to improve machinability, making it a top choice for copper casting manufacturing in the plumbing, industrial, and electrical industries.
