Electrolurgy’s Plated Zinc-Nickel is a durable, highly corrosion resistant coating that was developed in part as a replacement for Cadmium Plating. It is used in the protection of steel, cast iron, copper, brass and bronze. Zinc-Nickel is recognized as an environmentally safe alternative to cadmium electroplating. In specific applications, Zinc-Nickel demonstrates equivalent, or better, corrosion properties when compared to cadmium. Zinc-Nickel is normally applied for corrosion protection purposes, and functions as a “sacrificial coating”, corroding before the base material. Zinc-Nickel can also replace cadmium in galvanic interaction applications where the coating is intended to minimize corrosion caused by the interaction of dissimilar metals.
Electrolurgy’s proprietary Zinc-Nickel XB is a beautiful RoHS-compliant black zinc-nickel coating intended for connectors and backshells. The new coating is Electrolurgy’s response to new environmental regulations that seek to reduce the use of cadmium. Zinc-Nickel XB is approved as defined by MIL-DTL-38999L, and offers the same level of electrical performance, harsh environment protection and temperature ranges as cadmium finishes. In addition, Zinc-Nickel XB and cadmium have similar electrical potential, so new parts can be easily integrated into existing applications without additional engineering or excessive downtime.
Zinc-Nickel XB is non-magnetic and non-reflective and ideal for a variety of applications including next-generation harsh-environment vehicles, electric drive vehicles, aerospace, mass transit, automotive, communications equipment, power generation and metering equipment.
Electrolurgy also offers RoHS compliant clear and yellow post-plate treatments for increased corrosion protection, specific torque-tension requirements, or color identification.
