MIL-C-14550

Widely used in the oil and gas and petrochemical industries for its lubricity and anti-galling properties, copper plating can minimize costs and increase efficiency by reducing galling of high alloy threaded parts. Copper electroplating is used as a strike layer, providing a base coat for additional plating as well as selective masking prior to heat treating. Other advantages of copper electroplating include: excellent electrical conductivity and solderability.
